摘　　要：路堑边坡稳定性分析是工程建设中的重要问题。在工程地质勘察的基础上,利用非线性有限元法,结合强度折减理论,采用有限元软件ANSYS对某顺层岩质路堑边坡的开挖变形进行数值模拟,分析了该顺层岩质边坡的变形破坏机制及其演变过程,为边坡的工程治理设计提供了合理的建议。Stability analysis of cutting slopes is an important issue in road construction.The nonlinear finite element analysis of a consequent rock cutting slope is carried out based on the engineering geology investigation.The excavation deformation of the consequent rock cutting slope is simulated by using the strength-reduction theory and ANSYS.The mechanism and evolution process of failure are analyzed.Some reasonable suggestions are put forward for the treatment of slopes.
