Project overview I. Project layout and main structures The total reservoir capacity of the project is 7 million m3, and the installed capacity is 26 MW. According to the Classification and Flood Standard for Water Conservancy and Hydropower Projects (SL252-2000), the project is classified as Grade IV. Arch dams, power generation and diversion structures, tributary diversion structures, power plants and booster stations are Grade 4 buildings, and construction diversion structures are Grade 5 buildings. The dam site is located at the gorge reach about 500m upstream of the confluence of Xushui River and its tributary Dajian River. The riverbed at the dam stop is narrow. The bottom width of the riverbed is about 30m, and the bottom elevation of the riverbed is about 1183m. The slope gradient of the slopes on both banks is between 35 ° and 60 °. The lithology of the dam site is granite diorite. There is no large fracture zone at the dam site. The structural features are mainly joint fissures and small faults, without serious adverse geological phenomena. Guanyinxia Hydropower Station is located on the beach on the right bank of Xushui River at the confluence of the mainstream Xushui River and the tributary Guanyinxia. The beach is relatively open and suitable for layout
