Numerical analysis of the impacts of deep foundationpit excavation on neighboring buildings

WAN Shun1,2,MO Hai-hong1,2,CHEN Jun-sheng1,2(1.School of Civil Engineering and Transportation,South China University of Technology,Guangdong 510640,China;2.State Key Laboratory of Subtropical Building Science,South China University of Technology,Guangdong 510640,China)  
In allusion to the deep foundation pit excavation with a complex environment surrounding,a method to simulate the process of foundation pit excavation is proposed considering the stability analysis of the stratum near the pit lines.By combining stratum stability analysis and three-dimensional finite element analysis,it is shown that stability analysis of the stratum will be helpful in judging the slip between the rocks at the bottom of the pit,and the use of the actual stratigraphic surfaces makes the result of the numerical simulation of the deep foundation pit more realistic,which can verify the feasibility of the method and also provide some new ideas for the analysis of the deep foundation pit excavation.
