... Abstract To study the construction mechanical characteristics of shallow buried large span subway station tunnel, the Shangxinjie subway station in Chongqing is selected to establish three-dimensional numerical model using Midas-GTS. The deformation and stress distribution of surrounding rock...

... Abstract Determination distance between two transport tunnels is very important problem and has influence on the stability calculation and tunnel designations. However, nowadays in Viet Nam this problem has many disadvantages. This paper introduces the studying on determination of optimal...

... Abstract Stability and potential failure mode of tunnels and underground rock caverns are directly related to the magnitude and orientation of the in-situ rock stress. In some cases, the high horizontal in-situ stress is essential in maintaining cavern stability, whilst in other cases the high...

... Abstract The tunnelling industry has the means to make any "hole in the ground" almost to any size and shape that is requested. The main challenge is to integrate such solutions in the long-term development and urban planning. The underground solutions must be cost-effective to compete...

... Abstract In the last few decades, many hydropower projects have been built in Vietnam. Most of the hydropower projects have tunnels with different length and width, constructed in different geological conditions, ranging from excellent rock mass quality in hard granitic rock environment...
