Abstract
After a literature survey, the application of 3D seepage-consolidation coupling FEM model based on Biot theory and Cam-Clay model for simulating deep excavation dewatering in soft soil is studied. A foundation pit in East-China is taken as an example and 3D finite element method is used to simulate the dewatering and excavation. Through the 3D finite element analysis, the three-dimension numerical method can be applied to study the deformation behavior of foundation pit and surrounding soil. The numerical simulation experience and data presented in the paper can be refereed in the design, construction and research of similar projects.
