Abstract

2D-FLAC was applied to analyze the excavation process and the state of reinforcement structure, the stress statethe displacements Contour Graphthe displacement vector mapthe final settlement and the stress condition of the reinforcement structure were concluded through numerical simulation in the different conditions which the foundation pit was supported and not supported. The calculating results showed that the design of pit supporting structure was reasonable.
