| 摘 要： | 分别采用弹性地基"m"法和快速拉格朗日有限差分法,分析了基坑边坡水泥搅拌桩重力式挡墙墙宽及其嵌固深度对挡墙墙顶水平位移的影响,同时,与某工程实测数据进行了对比.结果表明,采用这两种方法估算水泥搅拌桩重力式挡墙墙顶水平位移都是可行的.

| Abstract: | The "m" method of elastic foundation and the finite difference method of fast lagrangian analysis of continuum are used respectively to analyze the influence of different widths and embedded lengths of the gravity retaining walls of concrete mixing pile on the lateral displacement at the tops of retaining walls.Some useful conclusions are drawn.Meanwhile,the results are compared with the measurements of an engineering example.They show that both of the two methods are feasible to predict the lateral displacements of retaining walls,and could be references to design calculations. |
