针对渝怀铁路鱼嘴车站岩质路堑植被边坡，采用直剪切试验获得边坡表层绿色防护层的物理力学参数。在此基础上，选取5个影响边坡表层土稳定性的因素（坡度、土层厚度、重度、粘聚力、内摩擦角），采用数学及数理统计的方法进行敏感度分析，得出各影响因素的敏感度顺序为内摩擦角〉坡度〉重度〉土层厚度〉粘聚力，分析表明绿色防护层的内摩擦角是控制其稳定性的主控因素。%In view of the rock-cutting slope of Yuzui Station of Yuhuai Railway, which is protected by greening, the physical and mechanical parameters of the protection layer are obtained by direct shear test. The sensitivity of five influencing factors (slope angle, thickness, unite weight, cohesion, friction angle) of the protection layer' s stability of rockcutting slope are analyzed based on the parameters, and the sensitivity order of influencing factors is obtained as friction angle, slope angle, unite weight, thickness, cohesion. The results show that the friction angle is the most important factor to help the stability of protection layer.
