摘　　要：边坡临界滑动场方法是一种较新的边坡稳定性方法。该法与传统的边坡稳定极限平衡分析方法思路大为不同,在深刻领会其思路精髓的基础之上,不采取先确定滑动区域内各点的危险滑动方向,然后再追踪出临界滑动场的思路,而是采用最新的优化算法和声算法对其进行了模拟。通过典型土坡算例的分析比较证明了本文方法的可行。The critical slip field method proposed by Prof.Zhu Dayong is a new tool for slope stability analysis,in which new procedures for the slope stability analysis are proposed.The applications of this method have been reported in China.The dangerous sliding directions for the points in the sliding zone are determined,and then the critical slip field can be obtained.Actually,the simulation of the critical slip field method can be obtained by using optimization algorithms.The harmony search algorithm is adopted to fulfill this simulation.The proposed method is demonstrated to be valid and efficient by performing the stability of two typical soil slopes.
