Abstract:

Applying ANSYS7.1 FEM program,the paper makes 2-D FEM simulation on the construction process of the side drift of Guanghualu station of line 10 of Beijing Subway by means of ANSYS 7.1，analyzes the effect of different working procedures of CRD method on the internal forces of the surrounding rockmass and the structure and on the settlement of the ground surface, defines the optimum construction scheme that can control the surface settlement effectively ,and makes 3D FEM simulation on the optimum scheme. Through the calculations and analysis, some conclusions are achieved,which can provide theareatical basis and technical guidance for the construction methods selected for the side arift of Guanghualu station and other similar works.
