Analysis of Slope Reinforced by Double Row Anti-Slide Pile Using Equivalent Plane Numerical Model

Generally, plane model is used to analyze slope reinforced with double row anti-slide pile reinforcement in slope engineering. In this paper, comparative analysis between traditional plane and three-dimensional numerical model is conducted based on strength reduction method. The results showed that the safety factor obtained by traditional plane and three-dimensional numerical model is different. A plane equivalent model with reduction factor which can reflect the same effect of double-row pile reinforcement using three-dimensional numerical model was proposed. The equation of reduction factor for plane numerical model is given by means of regression analysis. The problem of big error resulting by using traditional plane numerical model for analysis of slope reinforced by double-row anti-slide pile can be solved successfully.
