摘　　要：陕南地区地质情况复杂、地形变化多样,高速公路建设过程中不可避免会遇到路线穿过滑坡体,需要采取工程措施预防治理,提高其工程稳定性。本文从滑坡对公路工程的致灾机理着手,结合陕南某地高速公路建设中滑坡治理的工程实例,分析影响滑坡稳定性的主要因素,通过定性分析滑坡稳定性、定量计算剩余下滑力,合理采用抗滑桩治理为主、坡面锚固防护结合覆土反压为辅、加强截排水的综合治理措施,成功治理了特定工况下处于极限稳定状态的滑坡,为陕南山区滑坡治理积累了成功经验。The geological conditions in the southern Shaanxi region are complex and the terrain varies significantly.During highway construction,it is inevitable to encounter routes that pass through landslide bodies,necessitating engineering measures for prevention and remediation to enhance stability.This paper starts with the disaster mechanisms of landslides on road engineering,analyzing key factors affecting landslide stability based on a case study of landslide treatment during highway construction in southern Shaanxi.Through qualitative analysis of landslide stability and quantitative calculations of remaining sliding forces,a comprehensive treatment strategy is proposed,primarily using anti-slide piles,supplemented by slope anchoring and earth pressure counteracting,along with strengthened drainage measures.This successfully managed a landslide in a limit stability state under specific conditions,contributing valuable experience for landslide management in the mountainous areas of southern Shaanxi.
