摘　　要：针对香丽高速公路边坡地质灾害,在详细的道路工程勘察设计文件的基础上,结合现场踏勘调查,系统地研究了其边坡地质灾害的主要类型、发育特征和分布规律;提出高速公路等线性工程边坡灾害的基本地质条件、自然诱发因素、人类工程活动和灾害历史记录等完整信息评价指标。采用层次分析法、专家评分法与因素累积法相结合的研究方法,建立了线性工程边坡地质灾害易发性评价模型,并基于GIS平台完成了香丽高速公路边坡地质灾害的易发性区划。为指导香丽高速公路地质灾害的危险性评价及科学防治提供了重要依据,对类似山区道路等线性工程边坡地质灾害危险性评价研究与实践具有一定的示范作用和参考价值。Focus on theslope geological hazard of Xiangli expressway,systematic study was carried out to find the main types,development characteristics and distribution of slope geological hazards on the basis of detailed road engineering survey.A complete information evaluation index of linear engineering of expressway,including basic geological conditions,natural induced factors,human engineering activities and historical records of slope disasters,was put forward.The susceptibility evaluation model of slope geological hazards of linear engineering was established through the combination of Analytic Hierarchy Process(AHP),expert investigation method and factor accumulation method.The susceptibility zoning of the slope geological hazards in Xiangli expressway was completed,in terms of the GIS platform,which provided an important basis for the risk evaluation and scientific prevention of geological hazards in Xiangli expressway.This paper plays a certain demonstration role and provides reference for the research and practice of slope geological hazard assessment of linear engineering such as mountainious roads.
