Abstract

Abstract: Aiming at the critical slip surface in the slope stability analysis，the mutative scale chaos optimization algorithm will be improved．And the slope stability analysis of non-slice method is combined with chaotic logistic model search；the effective range of internal and external circulation the final slope of the screen to search the global optimal solution critical is resolved，which realizes the project of the slop in the general search for solving the critical slip su~aee．

Key words: slope, stability analysis, slip surface search, improved variable scale, chaos optimization
