The Calculation of Landslide-Thrust Based on Reliability Theory

Abstract

For current engineering of anti-slide piles, many problems exist in the calculation of landslide-thrust. Therefore, a new method based on the reliability theory combined with strength reduction FEM is introduced, and the landslide-thrust acting on anti-slide pile is researched here. In this method, the safety factor of slope can be caculated without assuming the shape and position of failure surface beforehand, the randomness of physical and mechanical parameters of slope are introduced, and the combined action of retaining structure and rock mass is considered. Meanwhile, the thrust distribution form and structural internal force can be calculated, which are also probabilistic. A case study shows that the calculation results are more reasonable and the applicability of proposed method is clearly dependable in calculating the landslide thrust.
