摘　　要：该文以江西永新抽水蓄能电站上水库为研究对象,基于现场水文地质调查、水文地质勘探、硐探、钻孔压水试验、地表水和地下水水质分析、地下水动态观测等资料,详细地分析了上水库的地层岩性、岩体的透水性、地下水位和流量的时空变化规律等水文地质条件,揭示了上水库可溶岩的分布、坝址区岩体透水性随埋深的变化、地下水位与正常蓄水位的动态响应关系以及上水库铜锣坪沟、带角岭沟和义松沟的地下水补径排条件,研究结果为上水库的水平和垂直防渗模式选择提供了参考依据。This paper takes the upper reservoir of Yongxin pumped storage power station in Jiangxi Province as the research object.Hydrogeological conditions such as the stratum lithology of the upper reservoir,the permeability of rock masses,and spatiotemporal variations rules of groundwater levels and flow rates in the upper reservoir area are analyzed in detail based on the data study of the on-site hydrogeological investigation,hydrogeological exploration,explorotary tunnelling,borehole water pressure test,surface water and groundwater quality analysis,and groundwater dynamic observation.It reveals that the distribution of soluble rocks in the upper reservoir,permeability changes of rock masses at different depth in the dam site area,the dynamic response relationship between groundwater level and normal water storage level,and the groundwater recharge,runoff and discharge conditions of Tongluoping Gully,Daijiaoling Gully,and Yisong Gully in the upper reservoir.The research results provide a basis for the selection of horizontal and vertical anti-seepage modes of the upper reservoir.
