Abstract:

The combination of shield method and shallowcovered mining method can be used to construct Metro stations, so as to improve the availability of shield and to reduce pipeline moving, building removing and traffic rerouting. In the paper, dynamic numerical analysis is made on the construction of a Metro Station on Line 4 of Beijing Metro, which is constructed by means of combination of shield method and shallowcovered mining method, by means of FLAC 3D numerical simulation software. The analysis result shows that the safety of the tunnel and the surrounding environment can be guaranteed, and the construction risks can be brought under effective control.

Key words: shield method, shallowcovered mining method, Metro station, numerical simulation
