| 摘 要： | 对基坑上部为粘性土、下部为砂土,其土钉支护结构的滑移面形状,采用有限元软件Plais和ANSYS对土钉墙滑移面进行了数值模拟,得到上部粘性土中近似圆弧型,下部砂土中直线型,其界线点在粘性土和砂土的分界面上的结论,并用得到的滑移面进行支护设计,取得较好的经济效益和社会效益,说明有限元软件模拟土钉墙滑移面是可行的。

| Abstract: | In view of the stratum features of foundation pit: upper part is clay soil and under part is sand soil numerical simulation of the slip plane of soil-nailed braced structure is carried out utilizing Plais and ANSYS.Analysis show clay soil is approximate to arc type,while sand soil has line type.Boundary points lies on interface of them.Practical supporting design receive good economic and social benefits,which show the application finite element software in slip plane in soil nailing wall design is practicable. |
