黏土边坡稳定性分析的一种快捷方法

为减少黏土边坡稳定性分析手工试算的工作量，提出一种快捷方法，先通过最危险的平面滑动面来确定滑动体的大小，在保持滑动体大小不变的情况下，通过简单的迭代计算将平面滑动面调整为实际滑动面，如圆弧滑动面等，并求出相应的稳定安全系数，用以判断边坡的稳定性．结果表明，本法所求得的边坡稳定安全系数均接近或小于文献所给出的结果．

Original and efficient method for stability analysis of cohesive slopes

A novel manual computation method to reduce the workload of stability analysis of cohesive slopes is presented. Firstly, the size of a slide body through the most dangerous plate slip surface is defined. Then modified is the plate slip surface through simple iterative computation to a surface which is similar to the real slip surface such as circular slip surface under the same weight of a slide body, and computed is the corresponding stability coefficient which is used to judge the stability of the cohesive slope. Three cohesive slope examples from references are analyzed with the new method. The results show that the stability coefficients given by the new method are approximate to or less than those from the references.
