摘要
天荒坪工程是目前国内同一厂房内装机规模最大的抽水蓄能电站,该工程第一台机组已于1998年9月并网发电,目前已有五台机组投入运行。文章简要介绍了天荒坪电站输水隧洞的设计与施工概况,该隧洞承受的内水压力水头、开挖直径、斜井施工难度等项指标均列国内外先进行列,本工程的设计与施工经验可供类似工程借鉴和参考。
Tianhuangping pumped storage power station ,with the total capacity of 1800MW, is the largest one in China that all units are installed in the same power station. This paper briefly introduces the design and construction of this water tunnel in Tianhuangping power station, which is listed in the advanced one in the world in terms of internal water head, excavation diameter and shaft construction. It is operated in 1998 and no abnormal occurs. The experience from this can be taken as a reference for the similar projects in the future.
