粤西山区花岗岩残坡积层高路堑边坡稳定性分析

Stability Analysis of High Cutting Slope of Granite Eluvium in the Western Mountainous Area of Guangdong

随着基础设施建设的发展,花岗岩残坡积层高边坡越来越普遍,边坡的坡体结构类型、变形破坏模式及其稳定性关系到防治工程的经济性和有效性。文章以云(浮罗定)茂(名信宜)高速公路K57+020~K57+200路堑右侧高边坡为研究对象,详细调查了边坡的坡体结构类型、分析研究了其变形破坏模式,在此基础上建立了高边坡稳定性计算模型,对高边坡的稳定性进行了详细分析。

With the development of infrastructure construction, high slope of granite eluvium is more and more common. The structural type, deformation failure mode and stability of slope are related to the economy and effectiveness of prevention and control engineering. Taking the high slope on the right side of K57 + 020 ~ K57 + 200 cutting of Yunluoding Maoming expressway as the research object, the structural type of slope and the deformation failure mode are investigated in detail. On this basis, the calculation model of high slope stability is established and the stability of high slope is analyzed in detail.
