摘要
在常规的概率极限状态理论基础上 ,分析了边坡体安全状态的模糊性 ,在此基础上构造了基于MCS以及FORM算法的模糊随机可靠度算法 ,分别就边坡体的滑动失效、渗透破坏两种失效模式作了参数敏感性分析 。
On the basis of conventional probability ultimate theory,through analyzing the fuzzy identity of bank slope stability situation,the fuzzy?stochastic reliability method based on the math theorem of MCS and FORM is established. By using this method,the stochastic parameters sensitivity analysis is implemented respectively on slope collapse and seepage failure of bank slope.Furthermore,the system failure of bank slope is introduced.
