Reliability Analysis of Slope by Point Estimate Method and Finite Element Strength Reduction Method

A new slope reliability analysis method was put forward in this paper,which combines finite element strength reduction method with Rosenblueth's point estimate method.The method was applied in to the safety and reliability analysis of the slope of Da Baoshan Open-pit iron mine to obtain the safety factor and reliability index.According to the analysis results,measures to reinforce the slope were suggested.
