摘要
边坡及边坡挡墙稳定性对于公路工程安全建设及运营具有重要意义。目前针对边坡稳定性分析已有较多研究,而边坡挡墙稳定性分析计算很少有实际工程案例可供参考。文章以陕西省榆林市府谷老高川至郭家湾公路的两段边坡为例,依据土力学和相关规范中的理论基础,通过库伦土压力理论计算,对自然放坡的边坡和设置仰斜式挡墙的边坡分别进行稳定性分析研究,为两段边坡的设计提供有力的支撑。结果表明:在一定的条件下,文中涉及的自然放坡和设置仰斜式挡墙的边坡均能满足规范要求,所提出的计算方法具有一定的参考价值,可为同类工程的设计提供理论计算参考。
The stability of slopes and retaining walls is of great significance for the safe construction and operation of highway engineering.At present,there have been many studies on slope stability analysis,but there are few actual engineering cases for reference in slope retaining wall stability analysis and calculation.The article takes the two slopes of the Fugu Laogaochuan to Guojiawan Highway in Yulin City,Shaanxi Province as an example.Based on the theoretical foundation of soil mechanics and relevant specifications,the stability analysis of the natural slope and the slope with inclined retaining walls are studied through Coulomb soil pressure theory calculation,providing strong support for the design of the two slopes.The results show that under certain conditions,the natural slope and the slope with inclined retaining walls mentioned in the article can meet the requirements of the specifications.The proposed calculation method has certain reference value and can provide theoretical calculation reference for the design of similarprojects.
