目前对边坡稳定影响因子敏感性的研究主要是针对边坡的内部因素,在分析路堤边坡稳定时,车辆荷载等外部因素对边坡稳定的影响不容忽视.本文同时考虑内部因素和外部因素,选择边坡土体重度γ、边坡土内摩擦角φ、边坡土粘聚力C、边坡坡度θ及交通量Q作为边坡稳定安全系数敏感性分析的影响因子,5个因子都具有广泛的分布随机性.以金鞭公路某标段路堤边坡为例,制定了5因子5水平的正交试验方案,利用传递系数法分别计算不同工况下的边坡稳定安全系数,再利用SP SS统计分析各影响因子对路堤边坡稳定安全系数的敏感性.研究结果表明:路堤边坡稳定性受内部因素和外部因素共同作用,影响因子敏感性大小依次为:边...

At present,the research on the sensitivity of slope stability factor is mainly aimed at the internal factors of slope.In analyzing the stability of embankment slope,external factors such as vehicle load have some influence on slope stability,which can not be ignored.The author selects slope soil weight γ,internal friction angle of slope soil φ,cohesion ofslope soil C,slope angle θ and traffic volume Q as factors affecting the sensitivity analysis of slope stability safety according to external and internal factors. Five factors have a wide d...
