摘　　要：采用现场调查和有限元分析方法,对羊曲水电站的厂房边坡的稳定性进行了分析,经分析认为,因受开挖卸荷的影响,坡体表部应力发生明显的分异,最大主应力总体为压应力,厂房外侧开挖边坡坡脚出现应力集中,坡脚至坡顶位移呈增大的趋势。Based on site investigation and finite element analysis method, the slope stability be analysised for Yangqu Hydropower Station Power- house. By the analysis that for the influence Of excavation unloading, slope surface stress obvious differentiation, the maximum principal stress overall compressive stresses, excavation slope toe lateral stress concentration, the toe of the slope to the top of slope displacement increases.

关 键 词：边坡 稳定性分析 有限元
