果多水电站枢纽布置及建筑物设计特点

Hydro-project Layout and Structures Design Features of Guoduo Hydropower Station

西藏果多水电站枢纽由碾压混凝土重力坝、坝身溢流表孔、左岸引水坝段及坝后厂房等建筑物组成,为西藏地区第一座碾压混凝土重力坝。设计过程中充分借鉴已建碾压混凝土重力坝的经验和教训,并结合当地高原气候条件,最终形成了电站设计的诸多特色。同时,通过工程实施过程中一系列设计优化和科研工作的开展,既提升了工程质量,又节省了工程投资。

Guoduo hydropower project in Tibet consists of RCC gravity dam, overflow at dam body, diversion damon the left bank, powerhouse at dam toe and other structures. The project constructs the first RCC gravity dam inTibet. A featured hydropower station is finally built through studying the experiences of built RCC gravity damsand analyzing the local climate conditions. Besides, a series of design optimizations and scientific researches arecarried out during the project implementation, improving the project quality and saving the project investment.
