In order to conduct more practical stability analysis for soil-rock slope, it was proposed to use Fortran language in a slope model to randomly generate rocks, based on which a soil-rock slope model was established. The stability analysis was conducted respectively for soil-rock slopes with five kinds of rock content. It is found that as the rock content therein increases, the slope stability gradually improves and the potential sliding surface of the slope also changes. The plastic zone penetration presents three typical modes: rock detouring, shunting and rock inclusion. The displacement in X direction is always the largest at the foot of the slope, and the maximum total displacement starts at the foot, moving to the middle of the slope and finally back to the bottom of the slope. The simulation results obtained by this method were compared to the calculation results of models with two typical equivalent strength parameters, and it is concluded that the safety factor calculated by this method is quite different from that obtained by the other two models, and also different in changing trend. In the future, this soil-rock slope model can be further optimized for other complex working conditions based on the mechanical characteristics and laws, with the influence of joints and cracks also taken into consideration.
