LI Liang, CHI Shi-chun, LIN Gao, et al. Slope stability analysis using extremum principle by Pan Jiazheng and harmony search method[J]. 2007, 28(1).DOI:
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-forces 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.
