摘　　要：针对东庄水库碳酸盐岩库段的岩溶渗漏问题,在区内岩溶勘察资料的基础上,对岩溶现象和试验成果进行了统计对比分析,对岩溶控制因素和发育规律进行了系统总结。结果表明:碳酸盐岩库段古老岩溶、古岩溶不发育,岩溶主要为岸坡浅表部位发育的近代岩溶;区内不存在大规模的深部岩溶和管道系统,岩溶行迹多沿沟谷或结构面发育,以小规模的溶孔、溶隙为主。因此,区内岩溶发育程度整体较弱,采取合理的防渗处理后,东庄水利枢纽工程不存在大的岩溶渗漏问题。For the karst leakage part of the Dongzhuang Reservoir,on the basis of the karst exploration data,the karst phenomena and test results were statistically analyzed,and the karst controlling factors and development laws were systematically summarized. Research results show that paleo-karst and old-karst did not been developed,and the karst in the reservoir region mainly developed along the river since the Quaternary. In the reservoir,there had no large number of deep karst and karst pipe system through exploration. The modern karst mainly developed in valley or structural plane,and the type gives priority to small-scale karst hole or karst gap. In the region,there is weak for the development degree of karst and Dongzhuang Reservoir does not exist serious problem of karst leakage with reasonable seepage prevention.
