摘　　要：高速公路路基边坡可能由于岩土体条件特殊、施工防护不到位、车辆荷载作用等原因而滑坡,破坏路基结构,威胁车辆通行安全。为此,全面防护及加固路基边坡具有必要性。文章以某高速公路工程为例,通过对路基边坡滑塌特征及成因的分析,提出挡土墙、拱形骨架、三维网植草等综合型路基边坡滑坡治理方案,阐述板桩墙和预应力锚索的施工流程及技术要点,有效加固高速公路路基边坡,避免滑坡事故的出现。Expressway roadbed slope may slide due to special conditions of rock and soil mass,inadequate construction protection,vehicle load and other reasons,damage roadbed structure,threatening vehicle safety,comprehensive protection and reinforcement of roadbed slope is necessary.This paper takes a highway project as an example,through the analysis of the characteristics and causes of the roadbed slope collapse,puts forward a comprehensive roadbed slope landslide treatment scheme such as retaining wall,arch skeleton,three-dimensional mesh grass,and expounds the construction process and technical points of sheet pile wall and prestressed anchor cable,so as to effectively strengthen the highway roadbed slope and avoid the occurrence of landslide accidents.
