通过对三维与平面应变状态下无支撑及多道支撑的基坑开挖模拟，对基坑的坑角效应进行较为深入的研究，包括考虑几何尺寸对基坑角部效应的影响，具体表现为对墙体变形及坑外土体位移的影响。当基坑开挖宽度较大时，相邻墙体的作用较强，基坑角部效应范围较大，约为5～7倍开挖深度，此时应考虑凸出现象的影响，同时坑外土体相应位置也将产生较大位移。

Based on the simulation of the three?dimension and plane strain condition excavations, with non?support and multi?support, the corner effect of the foundation excavation is conducted with a more in?depth research, including consideration of the geometric dimensions of the corner effect. The specific effect is reflected on the wall deformation and the displacement of soil outside the foundation excavation. When the excavation width is larger with stronger effect on the wall, the corner effects are relatively outstanding, with the sphere of influence about 5~7 times of the depth of excavation. At the same time, the convex effect should be considered fully. The displacement of the soil outside corresponds to convex point will be also more obvious.
