摘要
洪家渡水电站位于中国贵州省乌江干流北源，是乌江梯级的龙头电站，是国家“西电东送”首批开工项目之一，工程于2005年6月竣工。枢纽由拦河坝和左岸的溢洪道、泄洪洞、引水发电系统等建筑物组成。坝址位于高山峡谷岩溶地区，坝高179．50m，是国内外在建高面板堆石坝之一。在大坝设计和施工中采用了等宽连续窄趾板、冲碾压实等多项新技术。本文就洪家渡面板坝设计和施工技术进行介绍。
Hongjiadu hydropower station is located in the northern source of the main stream of Wujiang river in Guizhou province. It is the first stage of the cascade hydropower stations on Wujiang basin and one of the first lot of the projects of ＂ the power delivery form the west to the east＂ in China. It retained water in April, 2004 and the first unit was put into operation in July at the same year. The project is composed of a barrage, spillways on the left band, discharging tunnels. The dam site is located in the karst area with high mountains and valleys. The 179.5m dam is one of the high concrete - faced rockfill dams under construction at home and abroad. Now the dam fining reaches the elevation of 137m with an embankment of 6.5 million m3. The dam experienced two flood seasons of 2002 and 2003. Many new technologies have been applied to its dam design and construction, like continuous narrow plinth with equal width and impact roiling. This paper introduces the design and construction technologies of concrete- faced rockfill dam of Hongjiadu hydropower station.
