A solution to the stability coefficient of slope is obtained by establishing a homogeneous soil slope model and using FLAC - 3D software with the strength reduction method built in itself. The paper systematically studies the sensitivity factors of slope stability. The safety factor of slope stability and the plastic area are taken as the slope failure criterion. In order to find the relationship between the stability coefficient and the mechanical parameters of rock mass,and to find the most sensitive factor,only one parameter variable is changed. The re-sults show that the sensitivity of the angle of internal friction is the highest,and cohesive strength and soil weight are less sensitive. There is no permanent quantitative relationship between cohesive strength and soil weight.
