【Abstract】 The basic principle of Rosenblueth moment estimation method and its application into probabilistic analysis of slope stability are presented. The safety factor,reliability index and failure probability are given with this method. This method can combine the conventional safety factor with probabilistic analysis. A dual index system is setup to assess slope stability with safety factor and reliability index. As an example,the stability of Yancun landslide is assessed,and the results are tallied well with the practical case of the landslide.更多还原
