摘　　要：以某项目1#段扶壁式挡土墙为工程背景,采用ANSYS通用有限元分析软件建立空间实体模型,对扶壁式挡土墙的结构变形和结构应力进行分析,计算中考虑土体与挡墙之间的接触非线性。计算分析表明:扶壁式挡土墙在荷载作用下的变形和应力较低,具有足够的安全储备;扶壁板之间墙面板的中心位置附近有最大的水平位移,在扶壁式挡土墙设计中需要注意墙面板的刚度问题;墙面板、扶壁板、踵板、趾板的角隅位置通常存在较大的拉压应力,在工程设计与施工中需要给予关注。With the#1 buttressed retaining wall of a project as the engineering background,ANSYS general finite element analysis software was used to establish a spatial solid model to analyze the structural deformation and structural stress of the buttressed retaining wall.The calculation analysis shows that the project’s buttressed retaining wall has lower deformation and stress under load,and has sufficient safety reserves.The horizontal displacement near the center of the wall panel between the buttress panels is the largest.In the design of the buttress retaining wall,it is necessary to pay attention to the rigidity of the wall panels.The corners of wall panels,buttresses,heel boards and toe boards usually have large tensile and compressive stresses,which need to be noticed in actual projects.
