大化水电站位于广西境内红水河上,第一期工程装机40万千瓦,年发电量20.6亿度。工程主要建筑物有两岸接头土坝、非溢流混凝土重力坝、河床式厂房和溢流混凝土重力坝及垂直升船机。主体工程分期施工,第一期修建右岸滩地围堰,河水由束窄后的深河槽(河底高程96～112米)下泄,进行厂房施工,同时在左 Dahua Hydropower Station is located on the Red River in Guangxi. The first phase of the project has a installed capacity of 400,000 kilowatts and an annual generating capacity of 2.06 billion kilowatt-hours. The main structures of the project include cross-strait joint earth dam, non-overflow concrete gravity dam, riverbed-type factory, overflow concrete gravity dam and vertical shiplift. The main project was constructed in installments. In the first phase, the right bank cofferdam was constructed. The river water was drained from the deep river trough (the river bottom elevation was 96 to 112 meters) after the narrow beam, and the plant construction was carried out. At the same time,
