For now, the engineering landslide caused by rainfall is increasing, but the current research mainly stays in two-dimensional space which neither tallies with the actual three-dimensional space, nor lacks the related research on the influence of the landslide-function anti-slide pile system under different rainfall conditions. Therefore, it is necessary to make a further discussion. With the example of Chayang station landslide, this paper has made a three-dimensional calculation model of the interaction between landslide and anti-slide pile by using ABAQUS numerical analysis. Based on the unsaturated soil theory, the ABAQUS numerical analysis adopts the fluid solid coupling method to simulate the distribution law of the landslide-function anti-slide pile under different rainfall conditions. The research shows that the unsaturated soil changes from negative pressure zone to positive pressure zone and the corresponding soil arch effect weakens. And with the increase of the slide mass depth, the influence sphere of soil arch effect is reduced gradually. In this paper, related research conclusions can provide beneficial references for theoretical analysis of the interaction between anti-slide pile and soil mass, anti-slide pile design and construction.
