Ground Characteristic Curve (GCC) describes the relationship between the initial stress of rock mass and the displacement of rock mass on the boundary of tunnels. Another way that indicates the relationship of support pressure and the level of Convergence Confinement of tunnels by percent. The using GCC to design supports in the underground constru...

Vietnam there is Hanoi capital with more than 10 million inhabitants, but still have no underground railway. Therefore, traffic jams have been a huge problem in Hanoi recent years. It happens daily trapping hundred thousand of vehicles, wasting time and billions of dollars, causing problems in all aspects of the society. The design and construction...

Large rock mass deformation around deep roadways in the weak rocks was a significantproblem in mining activities in Vietnam and other countries. The excavation of roadways leads to highreleasing stress, which exceeds the peak strength of spalling surrounding rock and causes it to enter thepost-failure stage. Tensile failures then initiate and devel...

Excavation of adits in the rock mass for underground mining will be changed the state of initial stress in the rock mass, besides established the new stress state in rock mass around openings, respectively. The secondary stress state has influence on the design of stability for adits. Nowadays the estimation of stress and deformation around adits i...

Soil materials have been often considered in saturated condition for landslide analyses, in which back pore water pressure has been indicated to be a cause of the landslide. In this paper, numerical simulations are used to analyze the landslide process at the river bank from the viewpoints of unsaturated soil mechanics. A coupled hydro-mechanical m...

Research design lining for utilities tunnel in the city based on state of "lining-massif soil" Nowaday, in order to resolve the problem of utilities tunnel in large cities is very necessary. The technical pipelines, power cables, plumbing, drainage, ... in the large cities such as Hanoi, Ho Chi Minh is still a problem with no explanation. Within th...

Addressing urban transport is a very timely matter, especially in the capital Hanoi and Ho Chi Minh City. In order to solve this problem, a solution has been proposed for the construction of overhead tram and subway lines. In fact, when constructing subway lines through historical sites, high population density, many surface structures, etc., the m...

Process simulation has been a widely used tool for design and analysis for more than 50 years and applied in different fields including computer science, manufacturing, business, environmental, and construction. Moreover, today it is arguably one of the most multifaceted topics that can face an industrial engineer in the workplace. However, the use...

Microtunnelling operations involve a complex interaction of processes that require a variety of supporting equipment and personal experience. They require the integration of different construction processes such as supply chain management for the machine or for material handling. Breakdowns of critical processes might directly affect the productivi...

Manual fracture mapping in tunnels, slopes, caverns, mines or other underground spaces is a time-consuming and, sometime, dangerous process. Therefore, this paper describes the software named Surface Mapper 1.0, which is written in Visual Basic 6.0 and a photogrammetrical method for dip and dip direction automated measuring and 3D model creation on...

One of the most important tasks of geologists in the field is to measure fracture orientations on exposed rock faces. Measurements of these fracture orientations are normally done manually using a compass-inclinometer device on exposed rock faces as well as in tunnels, caverns, mines or other underground spaces. Doing so can be time consuming and s...

Field measurements on the excavated rock surface are tedious and sometimes very risky, especially if working in unstable slopes. During slope stability studies, detailed measurements are required for a better and more accurate analyses but the problem comes if the slope is very wide and very high. In order to solve these limitations, GIS Laboratory...
