济南泉域重点地段地铁建设适宜性评价

为评价济南泉域重点地段地铁建设适宜性,分析了影响地铁建设的主要影响因子,选取岩溶顶板埋深、岩溶水位埋深、岩溶含水层富水性、岩溶水功能分区、隔水层厚度、裂隙水位埋深、裂隙水富水性、地表水体分布、孔隙水位埋深、孔隙水富水性、活动断裂共11个因子建立评价指标体系,采用GIS空间分析法及AHP确定隶属度及权重,根据模糊评价结果,将济南泉域重点地段地铁建设划分为适宜区、一般区和不适宜区,并给出了各主要交通干道地铁建设与泉水保护的可行性建议。

Suitability Evaluation of Metro Construction in Key Sections of Jinan Spring Region

In order to evaluate the suitability of metro construction in key sections of Jinan spring region, main influencing factors which will affect metro construction have been analyzed in this paper. By choosing 11 influencing factors, the evaluation index system has been set up, including karst roof depth, buried depth of kasrt groundwater level, water abundance of karst aquifer, function division of karst water, thickness of aquifuge, buried depth of fissure water, bwater abundance of fissure water, distribution of pore water, buried depth of pore water, pore water abundance and active faults. By using GIS spatial analysis method and AHP method, membership degree and weight have been determined. According to the result of fuzzy comprehensive evaluation, suitability of metro constructionin main sectons of Jinan spring region can be divided into suitable areas, general areas and unsuitable areas. Feasible suggestions have also been given to metro construction and spring water protection in main roads.
