清连公路沿线地质条件特殊,边坡问题突出,数量多、类型全。通过现场调查研究及统计工作,探明边坡灾害的结构类型、变形破坏类型、形成条件,概化了边坡灾变机理及变形破坏模式,对沿线的427个边坡进行了稳定性评价。在此基础上,提出了防治措施,可为山区公路升级改造工程中边坡灾害治理设计提供借鉴。
Qinglian highway along the special geological conditions, slope problems prominent, the number of types of all. Based on the field investigation and statistics, the types of structures, the type of deformation and failure, the formation conditions of the slope disasters, the disaster mechanism and the deformation and failure modes of the slope are summarized, and the stability of 427 slopes along the line is evaluated. On this basis, the prevention and control measures are put forward, which can provide reference for the design of slope disaster management in the upgrading and reconstruction project of mountainous highway.
