Abstract

On the basis of Beijing Three Gorges Building,this paper uses FLAC3D software to carry out dynamic numerical simulation of the excavation and supporting courses of deep foundation pit in Beijing Three Gorges Building project.Meanwhile,during excavation and supporting of foundation pit,deformation of the foundation pit is monitored in real time till the completion of excavation and supporting of the foundation pit.Through analysis and comparison between numerical simulation results and measured deformation of foundation pit,it is indicated that application of numerical simulation method during excavation and supporting of foundation pit is comparatively reliable and that steel pipe pilecompound soil-nailing wall can satisfy the requirements of stability of support in foundation pit.
