沙沱水电站枢纽布置特点与关键技术

Characteristics & Key Technologies of Pivot Layout of Shatuo Hydropower Station

沙沱水电站是乌江梯级贵州省境内的最后一级电站,是国家"西电东送"第2批建设项目之一。坝址位于乌江下游沿河县城上游7km处的狭谷喀斯特地区,枢纽由碾压混凝土重力坝、坝身溢流坝、左岸取水坝后厂房、右岸垂直升船机等建筑物组成。设计中充分利用地形地质条件进行枢纽建筑物布置,解决了工程建设中的一些关键技术问题。本文主要介绍了适应沙沱水电站工程条件的枢纽布置与关键技术,体现了工程与自然环境和谐一体的设计理念,形成了沙沱水电站独特的枢纽布置格局。

Shatuo Hydropower Station is the last one of Wujiang Cascade Station development within the boundaries of Guizhou Province,also one of the second batch of country construction projects for 'power transmission from West to East'.The dam site is located in a narrow Karst gorge of downstream Wujiang,and is 7km away from Yanhe County on the upstream.The pivot layout is composed of RCC gravity dam,dam body overflow section,powerhouse at the dam toe on the left bank,vertical ship lift on the right bank,etc.Due to make full use of the topography and geology conditions in design,this kind of layout solves some key technical problems in engineering construction.The article mainly introduces the pivot layout and its key technology that adapted to engineering conditions of Shatuo Hydropower Station,embodies the design concept of engineering in harmony with natural environment integration.It forms the unique pivot layout pattern.
