摘　　要：针对目前深基坑研究深度及广度仍停留在初步阶段,采用二维弹塑性有限元法,模拟基坑开挖中常用的挡墙式支护结构与土体的共同作用,针对各种不同参数的挡墙,计算挡墙、基坑周围地面及坑地的变形,分析变形与各参数的关系。得出土体与支护结构之间的相互作用及土体随开挖深度增加的变化。Considering the theoretical research of deep excavation was not enough recently, this paper simulates the interaction of supporting structures and earth in deep excavation by using two-dimensional elastoplastic finite element method. To counter various parameters, it calculates the deformation of supporting structure, ground surface and the bottom of deep excavation. It also analyses the relation between the deformation and each parameters. The result of the interaction between earth and supporting structure as well as change of earth with increasing of depth of excavation is obtained.
