摘要

为了研究斜坡含软弱夹层地基路堤边坡的稳定性及破坏机制，采用离心模型试验和数值分析方法进行了研究。研究表明：斜坡均质地基路堤边坡仍是呈现整体圆弧滑动破坏；而对于含软弱夹层地基路基边坡来说，由于软弱夹层的影响其稳定性有了明显的降低，并有利于张拉裂缝的产生和发展，路堤边坡不再是整体圆弧滑动破坏，而是部分土体沿着软弱夹层发生滑动破坏。

Abstract

The purpose of this study is to investigate the stability and failure mechanism of embankments on sloping ground with weak interlayer. Centrifugal model tests and numerical simulations are conducted; and some useful conclusions are drawn as follows. The failure mechanism of embankments on homogeneous sloping ground is still circular sliding. Due to the effect of weak interlayer

the tensile crack will emerge and develop easily; and the embankment will become more instable and slide along the weak interlayer.
