  • The fuzzy interval of limit state variable near its zero value was considered, ana a moael of fuzzy-random reliability analysis of slope stability was put forward. The influences of width fraction and migration fraction on the fuzzy reliability index of slope stability were studied in different situations including the variability of common soil parameters and the membership function distribution of fuzzy failure probability. Analysis result indicates that the slope of migration fraction and fuzzy reliability index curve decreases with the decrease of width fraction, which is irrelated to the variability and the distribution. For a certainty value of width fraction, the fuzzy reliability index decreases with the increase of migration fraction. The increase of the variability of soil parameters results in the decrease of the index. 3 tabs, 4 figs, 7 refs.
