| 摘 要： | 以国内某高台阶排土边坡为例,分别采用Bishop法、Morgenstern-Price法、Spencer法及余推力法,针对排土场不同失稳模式下边坡稳定性进行了研究。结果表明,对于高台阶排土场边坡,当基础存在薄弱覆盖层、自然地形较陡时,沿排土体内部近程滑动和沿排土体-地基界面滑动均为潜在可能失稳模式,相应边坡稳定性通过不同计算方法综合判定。

| Abstract: | In this paper, based on a slope of waste dump with high terrace in China,Bishop method, Morgenstern price method, Spencer method and residual thrust method were used respectively, The slope stability under different instability modes of waste dump is studied. The results show that, for high terrace waste dump slope, when the foundation has weak overburden and the natural terrain is steep, both the short-range sliding and the sliding along the soil foundation interface are potential instability modes, the corresponding slope stability is comprehensively determined by different calculation methods. |

| Keywords: | waste dump unstable modes slope stability remaining thrust method high terrace |
