| Abstract: | Based on Monte Carlo theory and first order reliability method,and with the help of Fuzzy probability and expansion criterion,the generalized fuzzy random reliability theory is proposed in this paper.With the side-slope failure mode and seepage failure mode,the calculation method of the generalized fuzzy random reliability for embankment system is formed.Furthermore,the reliability of Jingnan main dike of Yangtse River is analyzed,and some rules for embankment safety are deduced in this paper. |
