摘要
为保障开挖施工中边坡结构的稳定性,文中以会泽至巧家高速公路建设工程项目为例,对山区公路深挖路堑开挖高边坡稳定性展开研究。结合该项目的基本情况,根据深挖路堑开挖高边沿线的地质情况、土层物理性质、断裂带发育情况,建立山区公路高边坡力学参数模型;引进SSR分析法,计算深挖路堑开挖高边坡强度折减系数。通过对高边坡位移变形量的分析,得到结论,高边坡稳定性会随着下挖深度的增加而增加,其中,低液限黏土层的稳定性最差。
In order to grasp the stability of the slope structure in the excavation construction,take the construction project of the Huize to Qiaojia Expressway as an example,to study the stability of the high slope of the mountain road deep excavation cutting excavation.Based on the basic condition of the project,establish the mechanical parameter model of high slope of mountain road;with the introduction of SSR analysis to calculate the reduction coefficient of high slope strength;by analyzing the displacement deformation of high slope,the stability of high slope will increase with the excavation depth,among which the stability of low liquid limit clay layer is the worst.
