山区公路地质灾害评价模型探讨

Discussion on the Evaluation Model of Highway Geological Disasters in Mountainous Area

目前对公路沿线地质灾害的评价方法以定性评价为主,尚未形成一套行之有效的定量或半定量评价体系和方法。文章根据公路工程的特点以及现有的地质灾害评估理论和实践,并结合公路地质灾害野外调查情况,提出了公路地质灾害发育程度、危害性、发展趋势及危险性评价方法,可供有关部门参考。

At present,qualitative method plays an important role in evaluating the geological disasters along highway,and the quantita-tive and semi-quantitative assessment systemand method has not been established. Based on the characteristic of highway engineering and the existed geological disaster evaluation theory and practice,and combining the field investigation of geological disasters along highway,puts forward the assess method of the development degree,harmfulness,development trend and the risk of highway geological disasters,which can provide a reference for related department.
