| Abstract: | Considering the fuzziness of physical and mechanical parameters and stability limit state,the fuzzy random reliability method of gravity dam stability analysis calculation is adopted in this paper based on multi-slide surface gravity deep stability solution.For randomness basic variables,it transformed fuzzy variables to random variables using the equivalent;and the limit state of ambiguity is described by the form of membership based on fuzzy statistics experiments and expertise.The case study shows that the fuzzy random reliability analysis method is a new method which is more reasonable to evaluate the situation of gravity dam stability. |
