鄂西北山区高速公路建设中深路堑边坡开挖后失稳的情况较为突出。结合实例，分析了滑坡产生的原因，评价并计算了滑坡的稳定性，总结了该类型滑坡多为软弱夹层发育片岩边坡受顺层及节理控制，同时在施工和降雨的共同作用下诱发。

The instability of deep cut slope after excavation is serious in the construction process of highway in northwest mountains in Hubei province.In this paper the mechanism and the stability of the landslide are analyzed.The results show that this type slope is formed mainly by schist with weak interlayer,and it will be instability with effects of the construction and rainfall.
