【Abstract】 In this paper, the method for the application of reliability analysis approach to the soil-nailed slope stability calculation has been discussed. Based on limit equilibrium method, an equation for the structure in limit state is deduced and an analysis of the related parameters on soil-nailed slope is made. Then the authors point out that the Fiessler method is a effective and rational method to calculate the reliability index. In the end of paper, some influences caused by the variation of the parameters on soil-nailed slope are discussed.更多还原
