摘　　要：针对高速公路地质选线仍然以案例分析为主,缺乏通用性定量分析模型的现状,以某高速公路为背景,在分析文献与案例的基础上,提出地形地貌、地层岩性、地质构造、水文地质、环境地质、地震与新构造运动、不良地质和特殊岩土等8个影响因子,构建层次分析、模糊综合评价模型。基于地质调绘、地质勘察,遥感影像等原始资料,借助ArcMap的空间与属性分析功能,将地质影响因子分离,并分级量化。采用层次分析、模糊综合评价法对格栅数据进行加权叠加、模糊逻辑运算,形成格栅综合成本。基于Dijikstra算法原理,综合运用ArcMap内嵌距离成本分析、成本路径分析工具,实现全面考虑工程地质影响的最佳线路选择。The geological route selection of expressways is still based on case analysis,and there is a lack of universal quantitative analysis models.Taking a highway as the background,based on the analysis of literature and cases,8 influencing factors including topography,stratum lithology,geological structure,hydrogeology,environmental geology,earthquake and neotectonic movement,unfavorable geology and special rock and soil are proposed,and a hierarchical analysis and fuzzy synthesis evaluation model is constructed.Based on the geological mapping,geological survey,remote sensing image and other original data,with the help of the spatial and attribute analysis function of ArcMap,the geological impact factors are separated and classified and quantified.AHP and fuzzy comprehensive evaluation method are used to carry out weighted superposition and fuzzy logic operation on grid data to form comprehensive cost of grid.Based on the principle of Dijikstra algorithm,the ArcMap embedded distance cost analysis and cost path analysis tools are used to realize the best route selection considering the engineering geological impact comprehensively.
