| 摘 要： | 基于在莱芜盆地开展的1∶5万水文地质调查工作，详细论述了盆地东部地区水文地质条件，将区内地下水类型划分为松散岩类孔隙水、碳酸盐岩类裂隙岩溶水、碎屑岩类孔隙裂隙水与岩浆岩变质岩类裂隙水四类，并总结了其含水岩组富水性；分析了区内地下水补给、径流、排泄特征与地下水动态变化特征；通过收集分析区内钻孔资料，总结了岩溶区岩溶发育特征，发现区内岩溶发育主要集中在200 m以浅，以溶蚀裂隙、蜂窝状溶孔为主；对清泥沟断裂、兴隆山-高峪铺断裂、铜冶店-孙祖断裂等主要控水断裂进行分析，提出东泉、清泥沟、丈八丘三个岩溶水富水块段，分析了各块段的富水机理，并提出各富水块段允许开采地下水量，为地下水合理开发利用提供一定参考资料。

| Abstract: | Based on an 1∶50,000 hydrogeological survey, this work details the hydrogeological conditions of the eastern Laiwu basin, Shandong Province. The groundwater in this area is divided into four types, pore water in loose rocks, karsticfissure water in carbonate rocks, fissure-pore water in clastic rocks and fissure water in magmatic and metamorphic rocks. Then this paper summarizes their water abundance, and analyzes the characteristics of groundwater recharge, runoff, discharge and dynamic change, the characteristics of karst development in the area. It is found that the karst is concentrated above the depth of 200 m in the subsurface, dominated by dissolution cracks and honeycomb karst holes. The water-controlling structures include the Qingnigou fault, Xinglongshan-Gaoyupu fault and Tongyedian-Sunzu fault. Three karst water-rich sections are suggested, i.e. Dongquan, Qingnigou and Zhangbaqiu, each has distinct water-rich mechanism and permissive mining yield. These results provide a reference for reasonable exploitation of groundwater in this area. |
