天荒坪抽水蓄能电站上水库设计特点及技术发展
|
摘要
天荒坪抽水蓄能电站上水库库盆防渗型式系国内首次采用全库盆沥青混凝土护面防渗,防渗面积达28.5万m2,坝体分区充分考虑利用库盆开挖的土石混合料筑坝,主坝坝轴线布置成弧线。本文主要介绍上水库设计特点,以及目前抽水蓄能工程库盆防渗及筑坝技术发展情况。
The anti-seepage type of reservoir basin on Tianhuangping pumped storage power station is the first time in China to adopt the anti-seepage surface of asphalt concrete in the reservoir basin, with an impermeable area of 285,000 m2; The dam area is fully considered to use the earth and stone mixture excavated from the reservoir to build the dam, and the axis of the main dam is arranged into an arc. This paper mainly introduces the design characteristics of the upper reservoir and the current development of reservoir impermeability and damming technology in the pumped storage project.
