| 摘 要： | 基于滑面应力修正技术并取整个滑体为受力体，实现了对滑体的整体极限平衡分析。同时，利用Green公式将有关域积分转化为边界积分，而无需再对滑体进行条分。该方法数值特性好，亦可方便地将二维的成果向三维推广，从而实现满足全部6个平衡条件的三维严格极限平衡法。本文是二维部分的成果。

| Abstract: | By means of remedying stress on the slip surface and taking the whole sliding body as the loaded object, a global limit equilibrium analysis for the sliding body is proposed. Because all those relevant area integrals over the sliding body are transformed into the relevant boundary integrals through Green’s formula; meanwhile, no slices are necessary when implementing the proposed method. The proposed method enjoys excellent numerical properties and can be easily generalized to the three-dimensional situations in which all the six equilibrium conditions can be satisfied. This study demonstrates the application of the procedure to two- dimensional situations. |
