摘　　要：应用大型非线性有限元软件ADINA对某基坑开挖进行模拟分析,采用水泥土挡墙支护,建立基于ADINA的二维模型,模拟施工开挖的过程,根据模拟结果分析了基坑的位移和锚杆轴力分布的一般规律。In this paper,the process of excavation is simulated by using the large-scale non-linear finite element software ADINA,the engineering situation and the basic steps of simulation are introduced.According to the simulation results,the general rules of soil displacement and the axial force distribution of anchor are obtained,which would be good for further understanding the deformation characteristics of foundation pit and helpful for design.
