摘　　要：采用非线性有限元的方法从平面和空间两个角度评价了台阶状结构面岩体边坡的稳定性 ,并采用了线性回归的方法验证计算结果的可靠性。分析表明 ,非线性有限元的分析方法能较好的模拟岩质边坡受力状态、各结构面所处力学状态以及边坡的破坏过程。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.
