山区高速公路滑坡处治探索与实践

Exploration and Practice of Landslide Treatment for Expressway in Mountain Areas

文章以河池至百色高速公路K49+540~K49+760路堑左侧滑坡处治工程为例,对山区高速公路路堑边坡滑坡治理难题进行研究,分析了滑坡的影响因素及成因机制,并基于极限平衡理论的折线型滑动面推力传递系数法对滑坡进行稳定性计算分析,提出了针对性的滑坡治理方案。

With the left-side landslide treatment project of K49＋540 ~ K49＋760 section in Hechi-Baise Expressway as an example,this article studied the landslide remediation problems of expressway slopes in mountainous areas,analyzed the influencing factors and formation mechanism of landslides,then based on the sliding surface thrust transfer coefficient method of limit equilibrium theory,it conducted the stability calculation analysis of landslides,and proposed the targeted landslide treatment scheme.
