摘要

以某高速公路红层软岩路堑边坡为例,根据地表裂缝发育情况和坡体结构定性评价边坡的稳定性,采用传递系数法计算边坡开挖之后的稳定性系数,定量评价边坡的稳定性,最后提出两种边坡防治方案。研究结果表明,边坡开挖之后稳定性较差,在暴雨工况下极易发生滑坡,两种防治方案技术上均是可行的。本文针对红层路堑边坡开挖出现较大变形之后采用的分析方法和支护方案,可为类似工程提供参考借鉴。
        A red soft rock cutting slope of a highway is taken as an example,it's stability is evaluated according to the development of surface cracks and the slope structure.The stability coefficient of the slope after excavation is calculated by the transfer coefficient method,and the stability coefficient of the slope is calculated quantitatively.Finally,two kinds of slope control schemes are put forward.The results show that the stability of the slope after excavation is poor,and landslide is easy to occur under the rainstorm condition. The two prevention schemes are technically feasible.In this paper,the analysis methods and support schemes adopted after the large deformation of the red bed cutting slope excavation can provide reference for similar projects.
