Numerical analysis of excavation stability of transfer station of Jinan Metro

Abstract The influence of the excavating deformation on the surrounding environment should be extremely controlled in the excavation of metro transfer station and it is important to study the stability of excavation. Here we establish three-dimensional finite element models with the fluid-solid coupling effect aimed to perform analysis on the stability of excavation based on the background of the Jinan metro transfer station in this paper. The location is determined through simulation in which the maximum horizontal displacement of diaphragm wall appears as well as the maximum ground surface settlement. The research results can provide useful reference in analysis and calculation for other similar underground engineering excavation and construction design.
