基于强度折减法的抗滑桩位置对边坡稳定性影响的数值分析

在滑坡治理中，抗滑桩仍是较为有效且应用较多的边坡加固方法。由于抗滑桩在边坡中的位置不同，其对边坡的稳定性影响效果也不同。通过三维数值模拟，分析了边坡中桩位与安全系数的关系。分析结果表明:抗滑桩位置改变，对安全系数有较大影响，中部影响较大，沿坡向向两边影响变小，且离边坡中部越远，其影响幅度越小。

Numerical Analysis on Effect of Anti-Sliding Pile Position on Slope Stability Based on Strength Reduction Method

Anti-sliding pile, in slope treatment, is still an effective and most widely used reinforcement method. Different positions of the piles give different effects on the slope stability. Through 3D numerical simulation, the relation between the pile position and the safety factor was analyzed. The result shows that, if anti-sliding pile position changes, the effect on the safety factor is great, wherein the effect on the middle part is large, while that on the both sides along the slope direction diminishes, and the farther away from the middle part, the smaller the effect.
