摘　　要：为正确识别路基沉陷灾害,应用灾害链式反应理论,研究了山区公路路基沉陷灾害的反应机理,提出路基沉陷发育阶段的划分方法以及路基沉陷风险的识别方法。以国际风险度指数R为依据,结合实际工程调查结果,对路基沉陷风险进行等级划分,并作为灾害治理的依据。In order to correctly recognize subgrade settlement disaster, the reaction mechanism of highway subgrade settlement disaster in mountainous area is studied using chain reaction theory. The classification method of subgrade settlement stages and the reorganization method of subgrade settlement risk are advanced. Based on international risk indicator R and combined with practical engineering survey result, subgrade settlement risk is classified, as the basis for disaster treatment.
