摘　　要：为进一步查明济南市区泉水与西郊岩溶地下水的水力联系,从地层结构、水动力场角度,通过抽水试验、示踪试验、制作Piper三线图等方法,进行了系统分析。研究表明,西郊刘长山—郎茂山—万灵山一带地下水流场不存在异常,两侧等水位线连续平缓,水位大致相同;刘长山北侧槐苑广场—九中—十四中一带在埋深350m左右揭露连续的岩溶含水地层,市区和西郊通过隐伏于岩浆岩体的三山子组地层岩溶发育段存在水力联系。市区泉水与西郊岩溶地下水水化学类型一致,二者具有相同的演化环境,水力联系密切。In order to further identify hydraulic connection between Ji'nan springs and karst groundwater in western suburbs,from the perspective of stratigraphic structure and hydrodynamic field through pumping tests,tracer tests,and Piper trilinear diagrams making,hydraulic connection between the two has been analyzed in this paper.It is showed that there is no abnormality in the groundwater flow field in Liuchangshan—Langmaoshan—Wanling Mountain in western suburbs,and the water level is about the same on both sides with a continuous and gentle isohyaline line.A continuous karst aquifer has been revealed in Huaiyuan Square—No.9 Middle School—No.14 Middle School on the north side of Liuchangshan at a depth of about 350m.There is a hydraulic connection between the urban area and the western suburbs through karst development section of Sanshanzi formation,which is hidden in magmatic rock body.The spring in the urban area and the karst in the western suburbs are of the same hydrochemical type.They two have the same evolutionary environment and close hydraulic connection.
