Ageing structures require periodic inspections to identify structural defects.
Previous work has used geometric distortions to locate cracks in synthetic
masonry bridge point clouds but has struggled to detect small cracks. To
address this limitation, this study proposes a novel 3D multimodal feature,
3DMulti-FPFHI, which combines a customized Fast...
This research presents monitoring data from a complicated case: the under-crossing of new three-line tunnels beneath existing three-line tunnels. The existing tunnels were monitored by electric level and wireless sensing network (WSN). By analyzing the monitoring data, the mutual influence patterns of the new three-line tunnels were identified, and...
It is highly challenging to comprehensively measure the deformations of large-scale tunnel structures because of the numerous individual segments of tunnel linings. Laser scanning and 3D deep learning (DL) can provide abundant geometric data and the ability to interpret such data automatically. To fill the gap in applying 3D DL to the segment-wise...
Point clouds provide a novel and effective alternative to understanding the structural behaviours of segmental tunnel linings. 3D deep learning (DL) has emerged as a promising technology capable of automatically deriving point-wise semantic and instance labels from point clouds. The utilisation of 3D DL in segment segmentation of tunnel point cloud...
Ground penetrating radar (GPR) is a vital non-destructive testing (NDT) technology that can be employed for detecting the backfill grouting of shield tunnels. To achieve intelligent analysis of GPR data and overcome the subjectivity of traditional data processing methods, the CatBoost & BO-TPE model was constructed for regressing the grouting thick...
The maintenance of in-service shield tunnel lining has become a critical issue in recent decades due to the rapid development of the metro system in China. The external load is one of the most important factors influencing the deformation and performance of the in-service shield tunnels. It is hard to evaluate the external load since it is influenc...
The performance maintenance of shield tunnels is of more and more significance with a great number of shield tunnels being put into service. The perception of deformation is an essential part of shield tunnel performance assessment because of the correlation between deformation and all kinds of affecting factors during service. While due to the nat...

Underwater shield tunnels take significant parts in urbanization, such as metro tunnels and utility tunnels. It is important to determine the structural performance and safety during service under complex changes in structure and surrounding ground. One of the influencing factors for underwater shield tunnels is tidal fluctuation. To study the effe...
Adjacent tunnel construction and environmental disturbances can lead to longitudinal deformation in pipe-jacking tunnels. The longitudinal deformation of the tunnel is closely related to the occurrence of joint dislocation, joint opening, and other defects. In view of the difficulty of obtaining 3D longitudinal deformation curves, a method is propo...
