| Abstract: | By combining the soil loss theory with the nonlinear Finite Element Method(FEM) based on the Winkler model, a new optimal design method containing different optimization objects for layers of struts system in deep excavation is established by integrating the displacement digraph. The method can unify the calculation of the inner force of structure and the deformation of soil. The optimal design parameters are position of each strut and depth of each excavation, which are solved by the complex method based on the optimization strategy proposed in this paper. |
