贵州黎洛高速路堑边坡典型破坏型式及防护措施

Typical Damage Types and Protective Measures of Guizhou Liluo Express-way Cutting Slope

贵州黎平至洛香高速公路为浅变质的变余砂岩与板岩,构造发育,岩体节理、裂隙发育,局部产生滑塌、崩塌现象。文章以该工程为例,分析了该路堑边坡存在的典型破坏型式,提出采用以骨架防护、生态植草为主的坡面防护和以挡土墙、锚杆框架、锚索框架为主的坡体防护等防护措施。

Guizhou Liping-Luoxiang Expressway is the blastopsammite and slate with epizonal metamorphism,with structure development as well as rock joints and fractured growth,and with local slumping and collapse phenomenon.Taking this project as the example,this article analyzed the typical damage types of its cutting slope,and proposed the application of protective measures such as slope surface protection based on framework protection and ecology grass planting as well as the slope guard based on retaining walls,anchor frame,and anchor-cable frame.
