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.
