摘　　要：以湖北十白高速公路栗石沟隧道洞口边仰坡的稳定性情况为例,就天然状况和暴雨工况2种工况,运用理正分析软件,采用圆弧滑动法确定滑裂面形状、瑞典条分法分析圆弧的稳定性,通过自动搜索最危险滑裂面来计算边坡的稳定性,定量计算了在自然工况和削坡卸载后的稳定性系数,对洞口边坡稳定性进行了定量评价。Taking the stability considering natural conditions of tunnel portal landslide of Hubei Shibai highway as an example and and storm conditions, by method and arc by arc sliding method, through automatic using Lizheng software, the Sweden slice searching the most dangerous sliding sur- face, this paper calculates the stability of the slope, quantitatively calculates the stability coefficient of hole stone ditch tunnel slope under natural conditions and cutting slope after unloading, and also quantitatively evaluates the slope stability.

关 键 词：边坡稳定性分析 削坡卸载 定量评价
