摘要
本文介绍了一种基于有限元应力分析的边坡稳定评价方法 ,讨论了边坡稳定安全系数定义的物理意义 ,介绍了搜索最危险滑动面的广义数学规划命题和模式搜索方法。
A method for stability assessment of slopes using pattern search technigue, which is based on finite element stress analysis, is introduced in this paper. The definition of the safety factor is elucidate and the mathematical programming technique for searching the slip surface is presented. Numerical examples of applying the method to various problems of slope stability analysis are given, which demonstrate that the method is efficient and reliable.
