【摘要】 结合泰安市岱岳区水文地质调查资料和实施27口钻井发现:在鲁中南泰莱盆地西部山区,碳酸盐岩裸露,崎岖不平的峰丛谷地、峰丛洼地地貌导致水力坡度大,地下水沿构造断裂呈线状快速径流,地下水非饱和,无统一水力联系,岩溶地下水分布极不均匀成为钻井取水的难点,寻找有利蓄水构造成为钻井找水关键;在盆地东部和南部靠近河谷的缓丘平原覆盖型岩溶分布区,水文地质单元上处于地下水径流排泄区,岩溶地下水丰富且呈层状、面状分布,水力联系密切,滞流形成饱水带,利于钻井开采地下水资源,但应着重关注火山侵入岩等隔水岩层的展布情况,综合分析岩溶含水层厚度、地下水水位和汇水条件。更多还原

【Abstract】 This work is based on combining hydrogeological survey data of Daiyue district,Tai’an city and implementation of drilling 27 wells. The results show that the mountainous areas of the western Tailai basin,central-southern Shandong are characterized by exposed carbonate rocks,rugged peak valleys and peak cluster depressions that resulted in large hydraulic gradients of landform,linear fast runoffs of groundwater along faults,non-saturated groundwater,no unified hydraulic connection of karst groundwater and extremely uneven distribution of karst groundwater,which make it difficult to find favorable water drilling sites. So to find favorable water storage structure becomes the key for water search by drilling. In the eastern and southern basin,gentle hilly plains near river valleys host karst zones of coverage type,where hydrogeological units lie in the discharge area of groundwater runoffs,with rich groundwater in layered and planar distribution,close hydraulic connections,and stagnation to form saturation zones,which are groundwater resources easy to drill. But it should focus on the distribution of volcano intrusive rocks and water resisting strata,as well as analysis of karst aquifer thickness,groundwater level and catchment conditions.更多还原
