利用粒子群优化算法求解土坡非圆临界滑动面

提出修复策略替换惩罚策略来修复搜索过程中可能出现的不合理滑动面,以更有效搜索最危险的滑动面。将粒子群中每个粒子比拟为滑动面,利用粒子群优化算法求解两个土坡的最小安全系数及其临界滑动面,同已有的结果比较,证明了文中提出的两种策略是合理有效的。

Solution of Soil Slope Non-circular Critical Sliding Surface with Particle Swarm Optimization Algorithm

This paper puts forward recovery strategy instead of penalty strategy to recover possible unreasonablesliding surface during searching so as to search for the most dangerous sliding surface more effectively.Comparing each particle in the swarm to a sliding surface,it is sought for the minimum safety factor and critical sliding surface of two soil slopes with particle swarm optimization algorithm.Comparing it with the existing results,it is proved that two strategies advanced herein are reasonable and effective.
