| 摘 要： | 在高速公路建设过程中，路堑岩质高边坡如何提高其稳定性与降低其工程造价这一对矛盾日益凸现。如何在边坡稳定性与工程造价之间选择一个最优的边坡放坡坡角是高速公路路堑岩高边坡工程中一项热点研究课题。根据京珠高速公路湖北大悟K34段的工作地质条件，分析了路堑岩质边坡最优坡角α代的确定方法，并用以指导治理施工，取得了较好的工程治理效果与经济效益。

| Abstract: | In the process of speedway construction,the contradiction between advancing the stability on the trench rock high slope and reducing engineering cost has been increasingly emerged.How to choose a most optimum slope angle for cutting has been a hot study problem between its stability and the low cost.In this paper,based on the engineering geology condition of K34 sect,Jingzhu Speedway in Dawu County,Hubei Province,the method for determining the most optimum slope angle for cutting has been analyzed,which is used to guide the construction of the engineering and some good treatment effects and economic benefits have been obtained. |
