摘要
介绍了斜坡潜在滑动面随机搜索的基本原理及其实现过程，建立了穷举法寻求临界滑动面及其破坏概率计算的随机模拟技术，完成了相应计算程序，并就其实用性、有效性，用泸州滑坡变形带算例进行了分析验证。
Random searching techniques for location of potential failure surfaces in two-dimensional slope stability analysis are presented. The method of determining the critical surface by multiple comparison and successive approximation , and calculating its failure probability is established. A computer program, Wslope (Ver 2. 0), developed by the author, features the stochastic generalized process for irregular trial failure surfaces in the search for the more critical ones. A case study of Luzhou landslides and deformation zone are given to illustrate the application of the methodology. The results show that the method developed herein is effective and practicable.
