Nowadays, computer technology has been developed rapidly, and numerical calculation methods have been widely used in geotechnics. Among them, the finite element method has developed into a powerful computational analysis tool. Based on the basic principle of the finite element strength reduction method, the article constructs the intrinsic model of rocky slope. The implementation process of finite element strength reduction method in ABAQUS for slope stability analysis is discussed. At the same time, we discuss the modeling process of evaluating the stability of jointed rocky slopes in ABAQUS software. Through the analysis of slope stability and destabilization mode, it can be seen that with the decrease of joint spacing s , the density of joints inside the slope increases, the safety coefficient of the slope decreases, and the destabilization mode of the slope is gradually transformed from the logarithmic spiral form to the folded line form. After applying the rocky slope management method of “anchor cable + inclined support wall + anti-slip pile”, the maximum displacement value is only 2.55mm, which indicates that the slope is in a stable state, and the anti-slip key has achieved the expected effect.
