3-dimention elastic-plastic finite element analysis of the deep foundation pit excavation and support

DONG Jianhua,ZHU Yanpeng(College of Civil Engineering,Lanzhou University of Technology,Lanzhou 730050,China)  
In order to further recognize works together and interaction between loess and flexible retaining wall,the deep pit of foundation excavation and support and loess are seen as a body to study.Combined with the reality project,3-D nonlinear FEM(ADINA) is used to analyze the performance of excavations and to simulate all the stages during construction of practical excavation.The finite element 3D model has been formed and analyzed retaining and protection structures internal force and deformation,displacement of soil behind wall,earth pressure,space earth pressure and plastic stress and strain.Some significant conclusions are remarked
