Abstract

Abstract

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.
