Abstract

The conventional methods for designing of anti-slide piles are based on constant value; it isn't consider the randomness and variability of the parameters, so the design of anti-slide piles will lead to some limitations: one is the methods can not give the safety of the slope; the second is the relatively conservative designing will lead to waste. But the reliability analysis method that consider the randomness of the parameters can measure the safety by rigidity probability, so that it also can make up difference that lie in the tradition anti-slides piles. Considering the reliability method, basing on computing formula of traditional slope stability, the evaluation model of slope stability is built. Using the M-C method and the single parameter sensitivity analysis method, the parameters in the design of anti-slide piles on safety factor and the reliability index are presented. It is demonstrated that the reliability index is affected obviously by the shear strength parameters, the gravity of rock and soil, the diameter of anti-slides piles, and the safety factors of slope sensibility is higher in some parameters such as rock and soil gravity, pile effective length, and pile diameter etc.
