摘要: 将离散单元法应用于山西某节理岩质边坡。通过对该边坡固定滑面及自动搜索滑面情况下的边坡变形破坏机理及其稳定性进行数值分析,找出了符合场地实况的边坡破坏模式,得出该坡体稳定性安全系数,并与极限平衡法稳定性评价结果进行了对比,结果较为吻合,为以后同类岩质边坡稳定性评价应用该方法提供了较好的借鉴。

Abstract: This paper presents the jointed rock slope stability analysis results by using the discrete element method. The factor of safety values are obtained from the jointed slope with fixed sliding planes and sliding plane with automatic searching techniques. These results are also compared with the limit equilibrium method and it is concluded that al results are similar.
