根据山东省沂南、费县两县的抗旱找水打井工作,利用物探定井、成井以及水文地质试验过程,对松林、西柳沟、响井、颜河庄4个村的水文地质条件进行了深入分析,总结了鲁南碳酸盐岩分布区两种典型的地下水蓄水模式,即断层蓄水构造模式和裂隙-岩溶蓄水构造模式。断层蓄水构造主要分布于该区中下寒武统地层,分布并不均匀和普遍,出水效果主要取决于断层的分布、张扭性质以及地下水径流方向的补给源,与地形情况关系不大;裂隙-岩溶蓄水构造在该区主要分布于奥陶系及上寒武统地层,裂隙岩溶发育,富水性好,发育较为广泛和普遍,打井出水成功概率高。对于两种典型地下水赋存模式的深入分析,可以为今后碳酸盐岩丘陵贫水区的地下水勘查工作提供思路。

[Abstract]
The water resource explorations in Yinan and Feixian of Shandong Province, the geophysical exploration, well constructions and hydrogeological tests were conducted to investigate the hydrogeological conditions in Songlin, Xiliugou, Xiangjing, and Yanhezhuang. . Two typical occurrence models of groundwater in the carbonate regions in South Shandong were summarized including the water storage structure model with faults and water storage structure model with fracture-karst. Water storage structure model with faults is mainly distributed in the lower and middle Cambrian System and it is not uniformly or widely distributed. The water effluent effect mainly depends on the distribution and tenso-shear property of the fault, and the recharge source of groundwater, while it isn’t related with the topography. However, water storage structure model with fracture-karst is mainly distributed in the Ordovician System and upper Cambrian System and it is widely spread. This model has good water effluent effects. The analysis of two typical occurrence models of groundwater can provide ideas for groundwater exploration in the carbonate water deficit regions.
