China produces and consumes most of coal in the world. This situation is expected to continue within a certain period in the future. Currently, Chinese coal industry is confronted with several serious problems relating to land resource, water resource, environmental, and ecological sustainability. Coal resource exploitation causes the permanent fracture and movement of strata structure, which h...

An efficient and modular numerical prediction model is presented to predict vibrations and re-radiated noise in buildings due to metro trains. The approach comprises of three weakly coupled problems: the dynamic vehicle-track-tunnel-soil interaction problem, the dynamic soil-structure interaction problem and the calculation of the acoustic response inside the rooms. The three-dimensional dynami...

A numerical prediction model is developed to quantify vibrations and re-radiated noise due to underground railways. A coupled FE-BE model is used to compute the incident ground vibrations due to the passage of a train in the tunnel. This source model accounts for three dimensional dynamic interaction between the track, tunnel and soil. The incident wave field is used to solve the dynamic soil-s...

Tunnel construction method using a tunnel boring machine (TBM) is commonly adopted for building underground infrastructure, such as railways, roads, sewers, or utility pipelines. TBM tunnelling entails precise guidance of the machine in the underground space, as well as effective construction management and project control. The research aims to address critical engineering and management proble...

Globally, there has been a remarkable growth in the number of underground constructions (UGC) such as railways, offices, hospitals and shopping malls. This expansion is result urban area extensions that are limited by availability buildable land. Underground construction can also be used to protect people from harshness outdoor conditions. The aim this research investigate impact hot regions. m...
