摘　　要：为查明峄城断块岩溶水系统岩溶发育特征及富水规律,通过对收集到的各类岩溶钻探资料统计与分析,并结合开展的1∶5万区域水文地质调查,对地表和地下岩溶特征进行了系统论述和总结,详细分析了岩溶富水规律及构造控水特征。研究表明,系统内奥陶纪马家沟群、寒武-奥陶纪九龙群三山子组地层岩溶最为发育,从补给区到排泄区,岩溶发育由弱到强,由浅到深,补给区岩溶以溶蚀裂隙为主,排泄区则多为溶蚀裂隙加溶孔、溶洞。区内裂隙岩溶发育程度在垂向上随着埋深的增加逐渐变弱,岩溶发育主要集中在20~180 m。地下水富集区地貌以山间谷地、洼地及山前平原区为主,广泛分布的可溶性岩石为地下水的存在提供了丰富的物质基础,复杂的地质构造则加强了岩溶水的富集,在断裂与岩脉交叉侵入部位,断裂强烈发育或互相穿插复合部位,开阔平缓的褶曲轴部以及断裂密集带等地段均是岩溶水的富集区。In order to find out the development characteristics and water-rich law of karst water system in Yicheng fault block,through statistics and analysis of various types of karst drilling data,combining with regional hydrogeological survey with the scale of 1∶50000,characteristics of the surface and underground karst have been systematically discussed and summarized,and the karst water-rich law and the characteristics of structural water control have been analyzed in detail.It is showed that karst developed well in the Ordovician Majiagou group and Sanshanzi formation in Cambrian-Ordovician Jiulong group.From the recharge area to the discharge area,the development of karst is changed from weak to strong and from shallow to deep.The karst in the recharge area is mainly dissolved fractures,and the discharge area is mostly dissolved fractures with dissolved pores and caves.The development degree of fractured karst in the area is gradually weakened with the increase of buried depth,and mainly concentrated in 20~180m.The landforms of groundwater-rich areas are mainly intermountain valleys,depressions and piedmont plains.The widely distributed soluble rocks provide abundant material basis for the existence of groundwater,and the complex geological structures strengthen the enrichment of karst water.The karst water-rich areas are located in the cross-intrusive parts of faults and dikes,the strong development or interpenetration parts of faults,the open and gentle fold crankshafts and the fault-intensive zones.
