摘　　要：以习水县仙源镇新场村某四级公路为研究对象,分析公路滑坡变形破坏特征和环境特征,进而对公路滑坡成因机制进行分析;根据《公路滑坡防治设计规范》(JTG/T 3334—2018),对该公路滑坡的防治工程安全等级进行划分;针对本段灾害特征和方案对比,制定出采用“108钢管桩注浆+A级混凝土护栏+边沟+路面+标线”措施进行综合处治,希望能够为其他公路滑坡类似工程提供参考。Taking a four-class highway in Xinchang Village,Xianyuan Town,Xishui County as the research ob⁃ject,in this article analyzes the deformation and failure characteristics and environmental characteristics of highway landslide,and then it analyzes the cause mechanism of highway landslide;According to Highway Landslide Preven⁃tion and Control Design Specification,the security level of the highway landslide prevention and control project is divided;Based on the characteristics and comparison of disaster plans in this section,a comprehensive treatment measures of"108 steel pipe pile grouting+A-class concrete guardrail+side ditch+pavement+marking"are formu⁃lated.It is hoped that it can provide reference for other similar projects of highway landslide.
