摘　　要：荒沟抽水蓄能电站地质探洞基本平行于尾水隧洞布置,位于两尾水隧洞之间,洞间岩体较薄,断层节理较发育,运行时可能沿断层节理向探洞渗水。且地质探洞与厂房顶拱岩体最薄部位仅为2 m,如果封堵处理不好,将会引起向厂房内渗水,严重时地质探洞与厂房连通,将会导致水淹厂房。文中介绍了荒沟抽水蓄能电站地质探洞封堵方案的确定过程,为类似工程的设计提供借鉴。The geological exploring adit of Huanggou pumped storage power station is parallel to the tailwater tunnel, and is arranged between two tailwater tunnels. The rock body between the tunnels is thin and the fault joint is more developer. Water seepage will occur into the exploring adit along the fault and joint during operation.The thinnest rock body between the geological exploring adit and top arch of the powerhouse is only 2m. Water seepage will occur into powerhouse if the plugging treatment is failing, and even is worse to submerge the powerhouse when the geological exploring adit and the powerhouse are connected. The paper introduces the determination process of plugging scheme for the geological exploring adit of the Huanggou pumped storage power station, which could provides reference for design of similar project.
