抗滑桩加固含软弱夹层路堤边坡稳定性分析

为了研究抗滑桩加固斜坡含软弱夹层地基路堤边坡的稳定性及破坏机理，采用离心模型试验进行研究。结果表明:软弱夹层对边坡稳定性有较大的影响，路堤边坡的破坏面不再是一般的整体圆弧滑动破坏，而是部分土体沿着软弱夹层发生滑动破坏。抗滑桩对含软弱夹层边坡有明显的加固效果，并且抗滑桩置于坡中时的加固效果要优于抗滑桩置于坡脚。

Stability Analysis of the Anti-slide Pile Reinforced Embankment Slope with Weak Interlayer

The purpose of this study is to investigate the stability and failure mechanism of the anti-slide pile reinforced embankment slope with weak interlayer. Centrifugal model tests are conducted and some useful conclusions are drawn. The results show that due to the effect of weak interlayer, the failure surface of the embankment slope will no longer the general integral circular sliding but slide along the weak interlayer. The anti-slide pile can significantly increase the stability of the slope with weak interlayer, and the reinforcement effect of pile setting in the middle is better than setting at toe.
