The slope cutting angle is an important design index, study on the cutting angle and slope stability, have great economic and social effect in the geotechnical engineering. Recently, the limit equilibrium method is mainly adopted to analyze the stability of rock slope, which is efficient in calculating the factor of safety of slope, but the stress-strain relationship of rock mass can not be described as well as the deformation and stress response of rock mass. Due to the rapid advances in computer technology and sustained development, the numerical method has been pushed to the forefront of geotechnical practice, which explores a new way for geotechnical designing, but it need more time in calculation the factor of safety of slope. So in order to combine both the advantages of the limit equilibrium method and numerical method, firstly, the factor of safety of slope with cutting angles are calculated by the limit equilibrium method, to obtain the optimum cutting angle; then, the numerical model is built according to the optimum cutting slope angle to study the stress and deformation of the slope rock mass, whose result can give some guidance for the real practice.
