摘　　要：大花水水电站库区碳酸盐岩广布,岩溶发育,岩溶管道水众多,坝基也直接处在二叠系茅口组(P1m)强可溶岩地层上,岩溶渗漏问题是水库建设的关键性地质问题。文章从地质背景、岩溶发育特征、地下水活动、岩溶水文网演化等几方面对水库岩溶水文地质特征进行了详细阐述,并重点对影响水库成库的库首岩溶渗漏问题及防渗处理进行了分析评价。Karst seepage is a key geological problem for formation of Dahuashui reservoir. The article describes karst hydrogeology characteristics of the reservoir in great detail from several respects such as geological background, activity of underground water, evolution of karst hydrologic network, and etc. , specially analyzes and appreciates karst seepage problem in the head of the reservoir that influences reservoir formation, as well as anti-seepage treatment.
