摘要

采用数值模拟技术分析了抗滑桩处理路堤滑坡的作用机理。分析方法采用强度折减法，桩土相互作用采用0厚度的弹塑性接触面单元模拟。给出了桩间距、桩的位置对抗滑桩处理效果的影响以及各种情况下桩的性状，结果表明：最大安全系数时的桩的布置位置与滑动形式有关，对于路堤滑坡而言，布置于坡脚处可以满足安全要求；适当减小桩间距可以提高路堤的稳定性，有利于土拱效应的发挥。

Abstract

The effects of the stabilizing piles on the stability of a slope are simulated. The shear strength reduction method is employed in the analysis

and the zero-thickness elastoplastic interface elements are adopted to simulate the soil-pile interaction. The effects of the spacing and position of the pile on the safety factor of the slope

as well as the behaviors of the piles under these conditions

are given. The calculated results show that under the maximum safety factor

the place where the pile should be installed is associated with the depth and position of the sliding surface; and for the embankment slope

installing piles at the toe of the slope is safe. Appropriate reduction of the spacing of the piles is beneficial to the improvement of stability of the slope and the exertion of the effect of soil arching.
