1. Preface
With the rapid development of Chinas highway construc-
tion, the extra-large bridges in the highway are developing
in the direction of long-span, new materials, and high qual-
ity, and new-type extra-large bridges have brought great
convenience to Chinas transportation [1, 2]. With the con-
tinuous increase of extra-large bridges, the number of dan-
gerous bridges and sick bridges is increasing every year.
According to the statistical survey data, 42% of the super-
large bridges in Chinas highways have been in service for
more than 20 years, of which 32% have suered from third-
and fourth-grade diseases, and more than 100,000 have been
identied as dangerous bridges [35]. For example, the
Hong Kong-Zhuhai-Macao Bridge, as the lifeline of Chinas
economy, will directly cause huge personal and property
losses once accidents such as collapse occur. According to
the statistics in Table 1, the bridge accidents in China in
recent ten years have caused serious casualties and heavy
losses of property.

With the rapid expansion of national highway construc-
tion and operation scale, the maintenance of super-large
bridges has also entered a rapid development stage, and a
large number of new technologies have been applied to the
monitoring and maintenance of bridges [6]. Use of advanced
Internet information technology, blockchain, big data, arti-
cial intelligence, and other new technologies has become a
systematic and modeled development trend of bridge moni-
toring and maintenance [7]. Traditional bridges will gener-
ate a lot of information from the beginning to the end,
including design drawings, construction, and operation
information, but the information will not be transmitted,
shared, and utilized during the project execution. Usually,
the design results produced by the design unit are handed
over to the construction unit with drawings [8]. According
to the drawing information, the construction unit uses the
cost software and the project schedule management software
to establish the implementation schedule, and after the con-
struction, the completed drawings will be delivered to the
owner [9]. The owner establishes the operation and mainte-
nance model according to the as-built drawings and inputs
the data into the integrated management platform of opera-
tion and maintenance, so as to realize the later operation and
maintenance management of the super-large bridge [10]. On
the whole, in the whole life cycle of the bridge, each data
information is kept in the main participating units in each
stage in isolation, and the information achievements in dif-
ferent stages cannot be reused, which easily leads to waste
of resources and increases the probability of errors [11].
The visualization and integration characteristics of BIM
technology provide a new solution for the maintenance of
highway extra-large bridges. Some researchers build the
BIM platform to manage the operation and maintenance
of the bridge, which mainly reduces the cost of visualization,
improves the ability of data integration and expression, and
realizes the data interaction and statistical functions [12]. At
present, BIM technology has carried out some research on
super-large bridges in the maintenance of bridges. Some
researchers put forward a three-dimensional visualization dis-
play of bridge health status based on BIM technology and
established a lightweight visualization model of the bridge
through Dynamo [13, 14]. Combined with the dynamic corre-
lation between the monitoring data collected by bridge sensors
and the BIM model, the three-dimensional visualization of the
bridge maintenance model was realized, and the function of
viewing monitoring data and automatic alarm was continu-
ously improved [1517]. By analyzing the monitoring data
of the bridge, some researchers put forward the design scheme
of the bridge health monitoring system based on BIM technol-
ogy and established the bridge health monitoring and mainte-
nance management platform through practical projects [18].
Some researchers proposed the BIM technology design of
the 3d visualization model of bridge diseases, which solves
the matching problem of bridge disease body properties, such
as dimension, using WebGL technology development of 3d
visualization software online; the bridge disease has realized
3d visualization displaying bridge structure cracks and local
disease and disease history evolution of bridge disasters. In
order to solve the current problems of scattered distribution
of bridge diseases and lack of global judgment, some
researchers carried out the distribution of bridge diseases
through BIM technology and developed a three-dimensional
visual bridge disease information collection, visualization,
and analysis system.
BIM technology, as a booster of informatization reform
of highway construction in China, has the characteristics of
visualization, renement, and collaboration, which greatly
reduces the construction cost, improves the informatization
level, and promotes the development of green buildings in
China [19, 20]. With the continuous application and promo-
tion of BIM technology, it is necessary to solve the mainte-
nance problem of highway extra-large bridges. Taking the
highway bridge as the research object, this paper establishes
the monitoring and maintenance of bridges based on BIM
technology, solves the lack of maintenance information ele-
ments in traditional BIM technology, develops the basic data
acquisition software of the BIM model, accurately locates the
disease position of highway bridges, and realizes the three-
dimensional visual information management system of brid-
ges, thus providing practical value for establishing the main-
tenance and management system of BIM highway bridges
[21, 22].
2. Application of BIM Technology in
Maintenance of Super-Large Bridges
The maintenance contents of the extra-large bridge mainly
include inspection, evaluation, maintenance, reinforcement,
etc. In this paper, BIM technology is applied to the mainte-
nance of super-large bridges. According to the information
elements required for the maintenance of super-large brid-
ges, an information model for the maintenance of super-
large bridges based on BIM technology is established, so that
the information of design, construction, inspection, mainte-
nance, reinforcement, and other projects can be eectively
linked in the whole life cycle.
2.1. Data Collection and Information Collation. In order to
establish the maintenance model of the super-large bridge,
the data collection scheme should be established rst, and

the technical data of the super-large bridge should be col-
lected, including design planning, geological survey, con-
struction records, completion reports, inspection data,
maintenance records, etc. After collecting the information
of the super-large bridge, sort out and analyze the useful
information in all the information; obtain the information
of the route number, bridge site, load, and geological condi-
tions of the super-large bridge from the planning and geo-
logical prospecting data; obtain the geometric information
of the components of the super-large bridge from the con-
struction drawings; obtain the construction process informa-
tion such as the construction date, responsible parties of
subprojects, and material grades from the construction
records; and obtain the operation and maintenance informa-
tion of the super-large bridge from the completion data,
inspection reports, and maintenance records.
As a key work in the maintenance of super-large bridges,
the disease information of the super-large bridge is stan-
dardized and discretized to collect and display the disease
information of the bridge when the maintenance informa-
tion model is established. According to the association of
bridge disease information, the relationship between the
content of the designed data table and each data table is
established, and the maintenance information database of
the super-large bridge realized by the BIM model is estab-
lished on the database server.
2.2. Establishment of Maintenance Information Model of
Super-Large Bridge Based on BIM Technology. The informa-
tion involved in the maintenance stage of the super-large
bridge is more extensive, mainly including drawings, con-
struction records, inspection reports, disease records, photo
data, etc. When BIM technology is adopted for integration,
it is necessary to extract the description objects of the model
and establish the relationship between objects and the infor-
mation points contained in each object according to the
technical characteristics. For the maintenance of super-
large bridges, it can be divided into the whole, parts, compo-
nents, diseases, maintenance, and reinforcement measures of
super-large bridges, among which the whole, parts, compo-
nents, and components can be derived from each child
object. The object relationship is shown in Figure 1, and
the arrow points to the parent object.
This paper mainly studies the disease object and
describes that the disease attribute of the bridge is related
to the component object and maintenance measures such
as crack lling and repair. Each object contains information
of levels/things. The whole object of the super-large bridge
contains information such as the name, line, coordinates,
and load grade. The part and component objects contain
information such as members, inspection, and evaluation,
and the component objects contain information such as
component geometry information, construction time, and
disease. The disease objects contain information such as dis-
ease type, degree, discovery time, and repair.
After determining the component division, determine
the neness of modeling. For the maintenance of extra-
large bridges, BIM models are mainly established for the
purpose of maintenance, which should reect the shape,
mechanical characteristics, disease distribution, and mainte-
nance scheme of components. At the same time, when the
model is too ne, the workload of modeling is greatly
increased, which is not conducive to the performance of
the 3d display system. How to determine the way and details
of component splitting has become the key of BIM
modeling.
2.3. BIM Model Component Division of Super-Large Bridge
Maintenance. The BIM model is dierent from the general
three-dimensional model, which not only contains the
three-dimensional geometric model of the super-large
bridge but also contains the corresponding information.
BIM model building needs to split the components accord-
ing to the super-large bridge. Too many components are
split too thin, which will be occupied by a lot of low-value
details, increasing the cost of useful information mainte-
nance and system operation. When the components are split
too thick, it will also lead to the loss of key information,
which limits the operation analysis work. The split method
of components is closely related to the acquired information.
The split component is the smallest unit of information
description, and its construction, damage, maintenance,
and other information are recorded in detail. As the basis
of carrying information, the rationality of building split
directly aects the utilization eciency of information. In
the BIM model, the geometry of components is bound to
the database component ID and linked to the component
information in the database.
2.4. BIM Technical Advantages. The visualization and inte-
gration characteristics of BIM technology provide a new
solution for the maintenance of super-large bridges. The
BIM platform is used for the operation, maintenance, and
management of super-large bridges, mainly including the
following:
2.4.1. Reduce the Cost of Visualization. Through Revit soft-
ware, object-oriented and parameterization are combined,
data and models are combined, and at the same time, it
has powerful graphics processing capability and open API
library, which facilitates secondary development and eec-
tively saves the cost of visualization.
2.4.2. Enhance the Ability of Data Integration and
Expression. BIM software has strong management ability
for models, and the data are stored in the model in the form
of model parameters. These model parameters can be
updated and queried in real time and can be related to each
other in dierent models. When the data in a certain place is
modied, all model data will be updated to ensure the data
consistency. Therefore, in the maintenance stage of the
super-large bridge, according to the BIM model in the con-
struction stage, by adding the data parameters of the main-
tenance module, all the data can be linked to the
components, and the data can be queried accurately.
2.4.3. Realize Data Interaction and Statistical Functions.
Based on the BIM platforms ability to manage components,
the statistics of data can be completed. Through the
3Wireless Communications and Mobile Computing
powerful API, the operation and maintenance management
system interacts with BIM software, and the data is sorted
and calculated by operating the model components, and
then, the calculation results are returned, thus avoiding mis-
takes in the manual statistics process and realizing ecient
management.
3. Realization of Monitoring and
Maintenance of Highway Super-Large Bridge
Based on BIM Technology
In the whole life cycle management of the super-large bridge
project, the operation and maintenance is the longest, and it
also involves the largest amount of information and man-
agement workload, with the cost accounting for 65%~70%
of the total project cost. At present, a large part of the exist-
ing highway bridges in China was built in the middle and
late last century. These bridges have been in service for many
years. However, most of the newly added bridges in China
are in the peak period of highway construction, and most
of them have the problems of short construction period
and hidden construction. At the same time, with the rapid
growth of trac volume and the continuous improvement
of transportation and carrying capacity in China, these brid-
ges deteriorate rapidly. The operation, maintenance, and
safety performance of super-large bridges have become the
most important issues.
At present, China has formulated the maintenance stan-
dards of super-large bridges, which mainly include facility
inspection, safe use inspection, reinforcement and mainte-
nance of components, and improvement of technical les.
Therefore, the maintenance of the extra-large bridge
includes manual and electronic inspection, safety status
management, decision-making, and establishment of data
les. The main process is shown in Figure 2.
3.1. Implementation of Manual Inspection Based on BIM
Platform. In the maintenance and management of extra-
large bridges, the safety state of extra-large bridges is deter-
mined by the state of each component in the extra-large
bridges. In the maintenance and management of super-
large bridges, the inspection is divided by components,
which are the most basic units for the operation and mainte-
nance management of super-large bridges. Accurate descrip-
tion of the safety status of components is the basis of
ensuring the overall safety status of super-large bridges.
Manual inspection and automatic monitoring are the data
sources to describe the safety status of components.
The manual inspection and automatic monitoring of
super-large bridges are generally done by a third party. When
the maintenance unit completes the manual inspection and
prepares the manual inspection report, a large amount of
raw data will not be given to management, but the visualiza-
tion of BIM technology provides a good solution.
According to the routine inspection work of the extra-
large bridge, it is convenient to ll in the Excel form with
the corresponding information and save the data after man-
ual inspection. Through secondary development, the BIM
function of manual inspection of super-large bridges is real-
ized and integrated into the Revit interface.
Through the manual inspection data of the Excel le,
each component will be accurate, so that clicking can realize
the view of the information of components in the model
project of the super-large bridge, and the attribute parame-
ters of each component will be added. Manually inputting
the family parameters of model components is a conven-
tional input method, which can be used when there are
few component models. When there are hundreds of family
components, this method is inecient in adding family
parameters. This paper will study Revit API, manage the
project model through family manager, and add family
parameters by using the AddParameter function of the
FamilyManage class, so that the parameters of family com-
ponents in the model can be added through secondary
development, and then, the parameters of components can
be added to the Revit interface, which is convenient for later
use and greatly saves the time and energy of repeated labor.
In Revit software, each component has a separate ID
number and a unique identication. In Revit software, the
ID number of a component can be viewed after it is selected.
On the contrary, the component can be located and selected
by ID number. The secondary development process of the
software is to identify components by their ID numbers.
When modeling, each component has a professional name.
In the form of manual inspection, the two identity attributes
of the component should correspond one to one, which is
convenient for computer reading and manual operation.
Therefore, before the inspection, the ID and name tables of
components are usually exported, which are used by manual
inspection and maintenance.

When the Excel le format is xed, the Excel le can be
read by writing a program to realize the data import function.
After the le is imported, the program will extract the ID num-
ber of each row in the Excel le, locate the component by this
ID number, and then get each family instance parameter
throughthe API, update the family parameter value to thesoft-
ware according to the Excel le format, and click the compo-
nent to view the new parameters of the updated component.
When the manual inspection is nished, the software
will rate the safety of each component. In the existing work,
the safety level parameter of the component has been added.
Through secondary development, the technical condition
level of each component is marked and recorded in the
parameter value. When the management and maintenance
personnel repair and maintain the components, click the
Extract Manual Maintenancebutton, and the software will
identify the safety level parameters of all components in the
model. The components with dierent levels will be placed
in the predened list container in the program and displayed
in the window through the Revit dialog box for managers to
use. The main parameters of the maintenance components
include the ID number, name, disease situation, mainte-
nance method, and other information.
The above method realizes the interaction and manage-
ment of manual inspection data, and the application of
BIM technology does not need complicated system develop-
ment. It only needs the model management capability of
BIM platform software to manage the component informa-
tion system and does not need manual secondary statistics,
thus ensuring the integrity of the original data and improv-
ing the accuracy of manual inspection and operation and
maintenance management. The use of BIM technology has
improved the maintenance and management eciency of
super-large bridges and can also solve the problem of iso-
lated information islands.
3.2. Automatic Sensor Monitoring Based on BIM Platform. In
the process of operation and maintenance of super-large
bridges, in order to grasp the safety status of super-large
bridges in real time and eciently, a large number of sensors
are generally installed on components to automatically mon-
itor the information of super-large bridges for decision
makers to analyze. With the increase of service time of
super-large bridges, a large number of dierent types of data
will be formed, which will play an important role in the
safety description of components. When these data are
stored in the health monitoring database, it will easily lead
to data separation, which will cause some diculty and
inconvenience for the maintenance and management of
the super-large bridge. Through the information exchange,
sharing, and integration of BIM technology, all the data
monitored by sensors are managed through the BIM
platform.
Through the secondary development of Revit, the sensor
data can be read and visualized. In this paper, the Excel le
of health monitoring data is used as the interactive le,
and in the process of reading sensor data, Revit is used to
operate the les in the folder, so as to realize the integration
of the Revit and Windows le system, and the data in the
Excel le is displayed by the Windows Form program. When
reading Excel les, the contents of Excel les are obtained (1)
by reading DataSet, (2) by storing the contents of Excel les
in rows through DataTable, (3) by other methods, and by
dening a class to store the data in each row, the stored Excel
les are bound to DataGridView for display. Figure 3 shows
the reading and visualization of sensor data.

3.3. Application of BIM Technology in the Maintenance of
Extra-Large Bridges. The maintenance of super-large road
bridges is an important part of road safety; if the mainte-
nance is not in place, it will cause serious disaster problems.
In the maintenance and reinforcement work of the road
bridge, the damage to the original structure should be
avoided as far as possible. After the maintenance work is
completed, the treatment eect is evaluated through the
comprehensive evaluation system. In this paper, based on
the BIM comprehensive platform and the actual situation
on site, the maintenance and health les of the super-large
bridge are gradually established to ensure that every disease
is recorded, so as to provide reference experience, save man-
power and material resources, improve maintenance e-
ciency, form maintenance records, and realize visual cloud
trace management.
4. Conclusion

Reinforced concrete bridges (RCBs) are essential elements of transportation infrastructure, necessitating ongoing inspection and maintenance to guarantee their durability and structural integrity. This research aims to develop an integrated framework for inspection and maintenance intervention in reinforced concrete bridges (RCB), leveraging the potential of as-is Bridge Information Modeling (BrIM). The methodology begins by converting 2D drawings into a 3D as-is BrIM model, facilitating a more accurate representation of the bridge’s current state. This is followed by creating a comprehensive bridge inventory, allowing for meticulous tracking of vital components and their condition. Subsequently, inspection data are acquired using advanced sensing technologies, enabling real-time data collection and analysis. Structural defects are modeled on the as-is BrIM model to enhance diagnostic capabilities, providing a visual representation of areas requiring intervention. The framework also makes it easier to create reports, ensuring that important information is efficiently shared with the right people. A thorough case study using a concrete bridge is used to show the effectiveness of the created framework. The BrIM framework’s potential to improve the bridge inspection and maintenance process was demonstrated by integrating inspection reporting with BrIM, which produced encouraging results. The research contribution to the body of knowledge is significant as the developed framework considerably enhances the administration of bridge inspection and maintenance procedures, resulting in greater efficacy by offering a thorough and clear picture of the bridge’s current state.

Block Yingmai 7 is structurally located in the western segment of the southern margin of the Kuqa Depression in the Tarim Basin. In the foreland basin, huge continental Mesozoic and Cenozoic strata have been deposited. In recent years, the Paleogene bottom sandstone section has been the main oil and gas exploration horizon. In order to further improve the oil and gas exploration effect of the Paleogene bottom sandstone in the study area and improve the accuracy of reservoir prediction, based on the related theory of sedimentology and petrology, this paper analyzes and studies the cores obtained by drilling in the Paleogene through laboratory core analysis experiments. The study shows that the Paleogene bottom sandstone is a braided river delta sedimentary system, and the sedimentary microfacies are mainly underwater distributary channels. The sandstone type is mainly light gray lithic feldspar fine sandstone, the sandstone debris particle sorting degree is medium-good, and the roundness is sub-edge-sub-circular. The microscopic characteristics of the reservoir are large pore throat radius, low displacement pressure, mainly intergranular pores, and good pore connectivity. It is a thin-layered mesoporous, medium-permeable, large-throat, and strongly heterogeneous reservoir. Finally, a classification evaluation table of reservoirs in block Yingmai 7 is established, and it is considered that the reservoirs of types I and II are enriched areas of oil and gas resources. The research results provide evidence for the prediction of oil and gas reservoirs.

End resistance is a dominant variable in the sinking process of super-sized caisson foundation, which is of great importance to the safe sinking of the caisson foundation. Based on soil excavation process of super large caisson foundation of the main tower of Changtai Yangtze River Bridge, the distribution characteristics and variation of earth pressure under the foot blade was analyzed using 3D finite element method at the first stage of soil excavation. Furthermore, the earth pressure was monitored in real time during soil excavation in order to analyze the influence of soil excavation process on the distribution of earth pressure. The analysis results of engineering practice showed that in the process of soil excavation from inner area to outer area, the end resistance of inner bulkhead and inner partition walls decreased, while the end resistance of outer bulkhead and outer partition walls gradually increased till the soil reached the failure state in the outer bulkhead area. The distribution characteristics and variation of the earth pressure can really reflect overall stress state of caisson foundation, which helps guide the safe sinking by soil excavation.

Recently, the digital operation and maintenance of large-scale public venues have received increasing attention. The traditional building automation system (BAS), which can only provide information in a non-visualized way, is incapable of meeting the complex requirements of modern operation and maintenance. Therefore, a 3D-based building information modeling (BIM) technology is needed to improve operation and maintenance efficiency. In the paper, a BAS-to-BIM combined strategy is introduced, and the BIM-based maintenance object framework for large-scale public venues is re-built. The conversion method and lightweight method for the BIM maintenance model are introduced and a new type of public protocol, which can be used to attain a unified protocol layer that serves the BIM model, is proposed. In addition, this article presents the application of technologies, such as virtual/mixed reality, to improve the convenience of operation and maintenance. Finally, a practical project of a snow-sports stadium is given as an example to elaborate on the benefit of the proposed method. It indicates that the functions, for example, information integration, visualization, and positioning, introduced by BIM technology can effectively improve the quality and efficiency of project operation and maintenance.

Reservoir wettability is an important indicator in the study of multiphase fluids in oil reservoirs. It involves the migration of crude oil from source rocks to reservoirs, accumulation in the reservoirs, and the entire process of crude oil development. The distribution characteristics of the wettability of sandstone reservoirs can provide a certain reference for the analysis of tight sandstone oil migration and accumulation mechanisms, and the exploration and development of tight sandstone reservoirs. This paper measures the contact angle between oil and tight sandstone by using the hanging drop method. Using the KRUSS DSA100S video optical contact angle measuring instrument, 25 unwashed oil tight cores and 62 washed oil tight cores are tested, respectively. Experimental analysis shows that the contact angle of the tight sandstones of the Taiyuan Formation in the Shenfu block of the Ordos Basin ranges from 50° to 150°, and the sample contact angles are concentrated between 70° to 110°. The wettability of the reservoir is mainly of the intermediate wet type, followed by the water wet type and the oil wet type.

The evolution of the construction industry is associated with the continuous implementation of new technologies. Building Information Modelling (BIM) has revolutionised the collaboration and data sharing processes in the architecture, engineering, and construction (AEC) industry. However, it needs to be supported by new technologies that can embrace digital construction by transforming the construction industry into a dynamic environment. There is a lack of understanding of the cutting-edge technologies that have emerged to help with the digital transformation of the construction industry. There is a need to understand all these technologies and how they can be leveraged holistically towards future BIM innovations. Therefore, this article conducts a literature review to evaluate how targeted cutting-edge technologies can be utilised to release the full potential of BIM from a technical perspective. A bibliometric analysis focusing on the co-occurrence of keywords related to various technologies, their links with BIM, and their related research themes was conducted based on the Web of Science (WoS) database holdings from 2010 to 2019. The findings demonstrate that one type of technology can help with solving a specific issue. However, using one technology alone does not solve an issue entirely. The current technology has been utilised independently and not as a coherent system. Thus, a weak information integration and management approach can restrict the leveraging of a smart BIM environment. This paper is not meant to be exclusive. Many new technologies, concepts, and ideas can be added to help realise BIM potentials that are not covered in this study. Furthermore, the analysis was based on the dataset retrieved from WoS and only included the literature in English. Based on those findings, the authors indicated a technology fusion to support BIM development.

Building Information Modelling (BIM) implementation is considered a daunting reality because majority of the construction players don’t know the potential benefits of the technology. Awareness of BIM benefits and its implementation could significantly increase project productivity and performance. This study is aimed to determine the influence of BIM benefits from the Malaysian construction stakeholders’ perception towards its implementation. The study was carried out using survey questionnaire. Out of 590 questionnaires 268 were collected that represent a sample size of 346. Results revealed that most of the construction companies lack of awareness about BIM technology. The statistical analysis showed that productivity, time, cost, clashes, and communication are the most essential BIM benefits that concerned the participants. The driving factors of implementation, on the other hand, were identified as Trust, respect, commitment, early involvement, and knowledge. It is also found that there is a significant relationship between BIM benefits and its implementation.

In the history of bridge engineering, demand has always been the primary driving force for development. Driven by the huge demand for construction since China’s reform and opening-up, Chinese bridge has leapt forward both quantitatively and qualitatively in three major stages, by completing the transition from “follower” to “competitor,” and finally to “leader.” A new future is emerging for Chinese bridge engineering. As an important part of China’s transportation infrastructure, the bridge engineering industry is facing challenges in this new era on how to support the construction of a new form of transportation. This paper provides a summary of the status of bridge technology in China, based on a basic analysis of stock demand, incremental demand, and management demand. It is our belief that the Chinese bridge engineering industry must fulfill three outstanding requirements: construction efficiency, management effectiveness, and long-term service. Intelligent technology based on information technology provides a new opportunity for innovation in bridge engineering. As a result, the development path of bridge engineering needs to be changed. This paper puts forward the idea of developing a third-generation bridge project that is characterized by intelligence, and discusses this project’s implications, development focus, and plan. In this way, this work provides a direction for the improvement of the core competitiveness of China’s bridge engineering industry.
