摘要
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 geotechni cal conditions in the study area, the main influencing Factors of collapse, landslides, mud-rock flow and other geological disasters were determined. The evaluation index system of engineering geology was established by the use of AHP method and engi neering geological model line selection analysis system was established by the use of engineering geology composite index. Combined with spatial analysis software features of Mapgis, the major influencing factors would be Superposition analyzed and the data would be treated by the property management system. After calculated the route engineering geology composite index, the right way would be chose.
