| Abstract: | The question of multi-supporting for deep foundation pits is discussed in this paper by using the methods of the plane strain finite element. Compared with traditional methods such as the static limit equilibrium method and the elastic resistance finite element method, this method is capable of researching supporting and soil as a system, coordinating the pile and soil and simulating the interface between them. It can give the deformation of the pit bottom and the ground surface, and the stress, bending moment of the supporting structure during different excavation stages. It is of important application value in the design of supporting structure. |
