在分析研究区所涉及的工程地质条件、水文地质条件和环境岩土条件的基础上,确定崩塌、滑坡、泥石流等地质灾害的主要影响因素,运用AHP法建立工程地质评价指标体系,采用的工程地质综合指数法建立工程地质选线分析系统模型,结合MapGis软件的空间分析功能,对各主要影响因素进行综合叠加分析,通过属性管理系统将数据导出进行处理,得出计算数据。经过计算得出路线工程地质综合指数,通过指数的比较确定优选路线。
Based on the analysis of engineering geological conditions, hydrogeological conditions and environmental geotechnical conditions involved in the study area, the main influencing factors of geological disasters such as landslide, landslide and debris flow are determined. The AHP method is used to establish the index system of engineering geological evaluation, Geological comprehensive index method to establish engineering geological alignment analysis system model, combined with the spatial analysis function of MapGis software, the main influencing factors are comprehensively superposed and analyzed, and the data is exported and processed through the property management system to obtain the calculation data. Calculated after the route engineering geology index, through the index to determine the preferred route.
