大化水电站位于广西红水河中游都安县与马山县交界处的大化镇,控制流域面积112,200公里~2。多年平均流量1,900米~3/秒,年平均含沙量达0.728公斤/米~3。坝址和库区多属石灰岩区,未发现岩溶渗漏现象。电站地质主要由薄层至中厚层泥岩夹粉砂岩、细砂岩,偶夹灰岩、薄层泥岩与灰岩互层,薄层灰岩夹泥岩组成。大化电站属低水头日调节的径流式电站,正常高水位为155米,有效库容0.7亿米~3,平
Dahua Hydropower Station is located in Dahua Town, at the junction of Du’an County and Mashan County, in the middle reaches of Hongshui River in Guangxi Province, with a controlled catchment area of 112,200 km2. The average annual flow of 1,900 m ~ 3 / s, the average annual sediment content of 0.728 kg / m ~ 3. The dam site and reservoir area are mostly limestone areas, and no karst leakage was found. The power station is mainly composed of thin to medium thick mudstone sandstone, fine sandstone, even sandstone, thin mudstone and limestone interbedded layer, thin limestone mudstone. Dahua Hydropower Station is a run-of-the-river runner with a low head-day regulation. The normal high water level is 155 meters and the effective storage capacity is 0.7 billion meters ~ 3.
