Abstract
Deep excavation is bound to cause deformation of supporting structure and surrounding soil, most deep excavation projects are located in downtown area, so the safety of the pit and surrounding environment must be guaranteed. In this paper, a deep excavation example in Tianjin is simulated by ABAQUS. Mohr - Coulomb model is selected. Foundation excavation and support adding are conducted step by step. Interaction between the pile and the soil is also considered. The deformation of supporting structure, surrounding soil and Bottom soil are calculated. The results were compared with field data and deformation regulation of supporting structure and soil is analyzed. Some meaningful conclusions the paper obtain can provide a reference for future similar projects.关键词
