摘　　要：文章首先对岩质边坡稳定性分析方法进行解析,通过刚体极限平衡分析法中的Sarma法,对岩质路堑边坡进行了计算分析研究,对不同高度的岩石路堑边坡和不同边坡坡比,其挖方土体的强度指标c、φ值应取何值,才可以使计算岩质路堑边坡稳定安全系数Fs达到1.3,保证路堑边坡满足的安全和稳定性要求。并对路堑边坡稳定性的相关影响因素进行了探讨,获得了一些有益结论,对实际工程具有一定的指导意义。Firstly, the stability analysis method of rock slope was analyzed in this paper, through the Sarma method of rigid body limit equilibrium analysis method, the rock cutting slope was analyzed in computing research, rock cutting slope of different height and different slope ratio, the index c, the strength of the soil excavation phi values should take any value,just can make the calculation of rock cutting slope stability safety coefficient of Fs is 1.3, security and stability of cutting slope meet requirements.And related influence factors of cut slope stability were discussed in this paper, some useful conclusions were obtained, the actual project had a certain guiding significance.
