基于有限元强度折减法，结合工程实例，利用软件ANSYS对不同倾角微型桩加固边坡以及倾斜微型桩的设桩位置、锚固深度和桩排距等桩身参数对边坡稳定性的影响进行了数值模拟分析。结果表明：微型桩加固边坡较优的倾斜角度为60°；随着设桩位置离坡顶距离的增加，边坡的稳定系数先增大后减小，当设桩位置距坡顶的相对位置为0.58~0.66，边坡的稳定系数较高；当桩排距为9倍桩径，边坡的稳定系数较高。研究结果为倾斜微型桩的设计与工程应用提供了理论依据，具有一定的普遍意义。

Based on the finite element strength reduction method and with a case study,different inclined micropiles,the mi-cropiles location,rock-socketed depth and pile spacing are simulated with the ANSYS finite element analysis software. The results show that the optimal inclined angle is 60°;with the distance of pile position from the top increasing,the stability coefficient of the slope increases first and then decreases;when the relative position of pile from the top is between 0.58-0.66,the stability coefficient is higher;when the pile spacing is 9 times the pile diameter,the stability coefficient is higher. The results of this study provide a cer-tain basis for the design and engineering application of inclined micropiles,which has a certain universal significance.
