摘　　要：山区高速公路建设形成大量路堑边坡,边坡变形滑坡病害时有发生,为了更有效、针对性地治理类似滑坡,以广东怀阳高速公路的实际滑坡治理工程案例为例,介绍了滑坡的工程概况、环境地质条件、建设及营运期滑坡病害情况,分析边坡所处环境地质和滑坡特征,采用赤平投影法和计算评估法进行边坡稳定性分析,提出了加固防护及监测方案,总结指出加固措施不足及提出类似边坡需强化加固。A large number of cutting slopes have been formed in the construction of expressways in mountainous areas,and slope deformation and landslide diseases have occurred from time to time.In order to control similar landslides more effectively and pertinently,taking the actual landslide control project case of Huaiyang Expressway in Guangdong Province as an example,this paper introduces the engineering overview,environmental geological conditions,construction and operation period of landslide,analyzes the environmental geology and landslide characteristics of the slope,uses the stereographic projection method and the calculation evaluation method to analyze the slope stability,and puts forward the reinforcement protection and monitoring scheme.It is pointed out that the reinforcement measures are insufficient and the similar slopes need to be strengthened.
