摘要
Slope stability assessment is a geotechnical problem characterized by many sources of uncertainty.In clas-sical reliability analysis,only the randomness of uncertainties is taken into account but the fuzziness of them is ignored.In this paper,a fuzzy probability approach and a fuzzy JC method are presented for the reliability analysis.The two methods have been applied to stability analysis of a certain slope of permanent ship lock in the Three-Gorges Project.The results obtained from these two methods are basically the same.However,compared with the fuzzy probability means,the fuzzy JC method can reflect the real situation better because it uses a fuzzy-based analysis applied to not only limit state equation but also mechanical parameters.
