| 摘 要： | 乌鞘岭地区高速公路是国道主干线的重要组成路段。开展高速公路沿线地质灾害研究,将为该区域高速公路沿线地质灾害防灾减灾提供基础依据。通过实地调查和分析,查明了乌鞘岭地区高速公路沿线地质灾害发育特征、时空分布规律及形成条件。结果表明:乌鞘岭地区高速公路沿线地质灾害类型主要为泥石流和不稳定斜坡,其中泥石流灾害具有分布广泛、发生频率高等特点;不稳定斜坡局部或零星分布,且现状危害轻;从时空分布规律上来看,具有条带性和集中性;形成条件包括地形地貌、地层结构、降雨、人类工程活动和地震;泥石流采取合理选线、监测预警、跨越疏导及生态恢复的防治措施;不稳定斜坡采取优化坡面形态、排水措施、工程治理结合植物防护的防治措施。

| Abstract: | Expressway in the Wushaoling is the important section of national trunk highway.Research for geological hazards along the expressway will provide the basis for disaster prevention and reduction.Based on field investigation and analyses,the development characteristics,temporal and spatial distribution and formation conditions of geological hazards along the expressway in Wushaoling were found.The results indicate that debris flow and unstable slope are the main types of geological hazards along the expressway in Wushaoling.Debris flow disaster distributes widely and occurs frequently.Unstable slope distributes locally or fragmentarily,and its hazards is gentle,which is characterized as zonal and concentrated features in terms of temporal and spatial distribution.Geomorphology,stratum structure,rainfall,human engineering activity and earthquake are considered as the formation conditions of geological hazards.Debris flow is controlled by applying for reasonable selecting lines,monitoring and warning,cross grooming and ecological restoration.Unstable slope is controlled by the means of optimizing slope morphology,drainage measures,engineering treatment combined with plant protection. |
