一、工程概况大化水电站位于红水河中游,系河床式电站。距广西南宁市154公里。本工程以发电为主,兼有通航效益。枢纽主要建筑物由混凝土重力式溢流坝、河床式厂房、左右岸接头重力坝和土坝、开关站及平衡重式垂直升船机组成。坝顶总长1166米。溢流坝布置于河床主河槽,为实体重力式和空腹重力式,最大坝高74.5米,最大堰高41米,共设13个溢流孔,每孔净宽14米,采用面流消能方式。坝址集水
First, the project profile Dahua Hydropower Station is located in the middle reaches of the Red River, Department of riverbed power station. 154 kilometers away from Nanning, Guangxi. The project mainly to generate electricity, both navigation benefits. The main structure of the hub is composed of concrete gravity overflow dam, river bed workshop, gravity dam and earth dam, switch station and counterweight vertical lift ship. Dam top total length of 1166 meters. The overflow dam is arranged in the main channel of the riverbed. It is a physical gravitation and fast-acting gravity type. The maximum dam height is 74.5 meters and the maximum weir height is 41 meters. There are 13 overflow holes each with a net width of 14 meters. Dam site catchment
