Abstract: In the mountain railway construction process, large-scale landslides often used the engineering measures of multirow anti-slide pile reinforcement to reinforcement. The current conventional method of calculation can not calculate the value of the thrust accurately as well as the sharing ratio by the anti-slide pile in each row. In this paper, using large-scale numerical ANSYS finite element software to study Liu Zhan Cao Jia Shan landslide. Using the numerical calculation to get the value of the thrust, and calculate the thrust ratio, this method provides more scientific and rational basis, also avoid those limitations of the former method, and provides a proven solution.
