摘　　要：荒沟抽蓄电站是黑龙江省首座全面投产发电的抽水蓄能电站,上水库采用主、副挡水坝+垂直防渗帷幕的局部防渗形式。为整体分析库区渗控效果,本文采用有限元计算软件Midas GTS-NX建立包含坝体、帷幕等整体库区的三维有限元渗流模型,分析计算大坝及库周的渗流特性,研究上水库大坝筑成后结合防渗帷幕的整体防渗效果,该研究对局部防渗抽水蓄能电站的三维渗流计算具有一定指导意义。Huanggou Pumping and Storage Power Station is the first fully put into operation in Heilongjiang Province pumped storage power station.The upper reservoir adopts the local anti-seepage form of main and secondary dams with vertical anti-seepage curtain.In order to analyze the seepage control effect of the reservoir as a whole,the finite element calculation software Midas GTS-NX is used in this paper to establish a three-dimensional finite element seepage model of the whole reservoir including the dam body and curtain,analyze and calculate the seepage characteristics of the dam and the reservoir circumference,and study the overall anti-seepage effect of the upper reservoir dam combined with the anti-seepage curtain after construction.The study has certain guiding significance for three-dimensional seepage calculation of local anti-seepage pumped storage power station.
