摘要
通过分析岩堆路基的特性,研究以崩坡积碎块石为主,自然状态下基本稳定、工程扰动后会发生危险的路基加固处理方法。根据理论计算和敏感性分析并结合工程现场的实际情况,确定了放缓边坡并清除大部分岩堆物质,设置抗滑桩进行加固处理的处治方案。目前该山区高速公路稳定、安全、景观协调,体现了综合设计方案适用性。
The characteristics of talus subgradeis analyzed to research the reinforcing technology forthe subgrade mainly composed of colluvial debris, which is basically stable under natural state butdangerous after engineering disturbance. By means of theoretical calculation and sensitivity analysis,the corresponding treating plan for the talus subgrade is determined according to the actual situation ofthe engineering field. Some reinforcing methods is applied to ensure the stability of the roadbed suchas slowing down the slope and removing most of the rock mass and setting up the present, the highway stability, security and landscape coordination in mountainous area reflect thesuccess and applicability of the integrated design scheme.
