摘　　要：文章针对云茂高速公路SJ4段边坡滑塌问题,基于滑塌边坡区域地质背景,分析路堑边坡、路堤边坡、桥墩前自然边坡的滑塌成因,提出先清坡后加固、“一坡一案”的处治思路与针对性方案,意在通过锚固加固、混凝土框格梁、护面墙与护脚墙等综合处治方法与措施恢复边坡稳固性。处治结果表明,高速公路滑塌边坡得到了有效处理与加固,实现了安全、美观、经济等预期目标。Aiming at the slope collapse problem in SJ4 section of Yunmao Expressway,based on the regional geological background of the collapse slope,this paper analyzes the causes of the collapse of the cutting slope,the embankment slope and the natural slope in front of the pier,and puts forward the treatment ideas and targeted scheme of slope clearing first and then reinforcement,"one slope and one case".It is intended to restore the stability of the slope through comprehensive treatment methods and measures such as anchoring reinforcement,concrete frame beam,facing wall and toe protection wall.The treatment results show that the expressway sliding slope has been effectively treated and reinforced,and the expected goals of safety,aesthetics,and economy have been achieved.
