Shimen water conservancy and hydropower hub project is based on power generation, taking into account flood control, irrigation and water supply in the county comprehensive utilization project. Dam type power plant installed capacity of 3 × 3200kW, the dam is a masonry gravity dam, the reservoir total storage capacity of 89100000 m ~ 3, flood control standards for 20 years, irrigated area of 2533hm ~ 3, and can meet the long-term Xixia County Water supply requirements. According to the design requirements, the dam foundation surface is placed in the middle and lower part of weakly weathered rock mass. The excavation height of the slope foundation of the dam foundation is 26m. The excavation depth of the riverbed section of the dam foundation is 6m and the dam length is 143m. The total is 4
