摘　　要：　左江水利枢纽系一低水头低Fr数(0.2～4.7)水流的大(Ⅱ)型水利工程。通过对坝址地形、地质、水文、交通、施工等条件的分析论证,选择辉村坝址并优选及调整了下坝线,确定左岸过坝建筑、河中溢流闸坝、右岸电站厂房的枢纽布局,采用大孔口低堰闸坝、河床式电站轴流转桨式厂房、水坡升船、消力戽消能工等建筑布置形式。工程建成后效果良好。The Zuojiang WR key project is a large(Ⅱ) type hydraulic project of low water head and low runoff. By analyzing the dam site topographic, geologic, hydrologic, communication and construction conditions, selected the Huicun dam site, regulated the upper dam line, determined the composition of the overdam architectural in left bank, overflow sluice in middle and powerhouse in right bank. And used the layout composition of big hole lowweir sluice, river bed propeller type power house, water slope ship lift and bucket dissipater.
