摘　　要：在高速公路建设过程中 ,岩质高边坡稳定性问题日益凸显了出来。采用离散化的数值模拟技术来模拟分析该类高边坡的稳定性 ,并据此提出合理、经济的防护治理措施是目前解决这一难题的有效途径之一。本文根据京珠高速公路湖北大悟 K34+ 134～ 15 8段的工程地质条件 ,利用 FL AC3D三维动态仿真模拟分析了其第二次滑塌过程及形态 ,并用以指导其治理施工 。In the process of expressway constructinon, the problems of stability of the rocky high slope of cut are increasingly emerging. The stability of this type of slope is simulated by the numerical modeling technique of discretization and it is one of the effective methods to resolve these problems that the valid and economic prevention measurements are advanced. On the basis of the engineering geology condition of Station K34+134～158 Da Wu Section of Jing Zhu Expressway in Hubei Province, the shape and process of the second slide are analyzed with the three dimensional dynamic simulation. The method is used to guide the engineering construction, and some resultful effects are obtained in the prevention and cure.
