| Abstract: | Based on the Bishop slice method,a calculation model is established for the analysis of slope reliability,and the rational polynomial technique is adopted to calculate the derivatives of the performance function at the design test point so as to simulate the reliability problems with the closed-formed performance function in actual engineering.No matter whether the performance function is linear or nonlinear,explicit or implicit,this method is simple and suitable.The calculation results of the reliability i... |
