Currently

the calculation method of landslide-thrust and internal forces of anti-slide pile in essence belongs to the fixed value method. However

for the lack of considering geotechnical uncertainties

inadequate and excessive support problems for the anti-slide piles cannot be ignored. Thus

based on strength reduction of finite element method

the reliability analysis method of landslide-thrust and internal forces of anti-slide pile is proposed. In this method

the limit analysis

finite element analysis as well as reliability analysis are included. In the calculation process

2-node beam element is used to simulate the stress condition of anti-slide pile; and the Latin hypercube sampling(LHS) method is used for reliability calculation; and above process is realized in the numerical calculation program. Landslide-thrust and internal forces of anti-slide pile are statistically analyzed; and function distributions can be achieved. With the control values of a given failure probability

the design values of landslide-thrust and internal forces can be accurately determined. Typical example analysis shows that the proposed method is significantly different from the general methods; it can reflect the slope present situation

overall characteristics and the variability of material parameters; and the results are closer to the reality.
