摘要
基于潘家铮极大极小值原理,结合和声搜索算法提出了一种土坡稳定分析的新方法。对给定的滑动面,利用和声搜索算法寻找出能使该滑动面具有最大抗滑稳定安全系数的内力分布,其间可以考虑土条发生局部破坏后的内力调整过程。同样利用和声搜索算法搜索出土坡最危险的滑动面。将该法应用于简单土坡、复杂土坡的稳定分析中,与传统方法计算结果的比较证明了新方法的合理和适用性。
A new method of stability analysis of slopes is presented based on Panjiazheng extremum principle and harmony search method. The harmony memory search method is used to locate the distribution of inner-forees acting on the sliding mass above the given slip surface, which endows the given slip surface the maximum factor of safety. The harmony memory search method is adopted to search the critical slip surface, which has the global minimum factor of safety. And also the new method is applied to stability analysis of two soil slopes. The comparisons of the computed results with that by conventional analysis method have shown that the new method is feasible and applicable to the slope stability analysis.
