| Abstract: | From the view point of plane and space, this paper evaluates the stability of rock mass with step_shaped joint planes by way of nonlinear finite element, and the reliability of the calculation results are proved by means of linear regression method. The results indicate that the nonlinear finite element method is able to provide a better simulation to the loading situation of rock slope, the mechanical state of each joint plane and the failure process of rock mass. |
