Design of Main Dam Zoning of Upper Reservoir and Dam Construction Materials of Xiangshuijian Pumped Storage Station

Gong Xuwei,Zhu Aili(Shanghai Investigation,Design and Research Institute Co.Ltd.,Shanghai,200434)

The main dam of the upper reservoir of Xiangshuijian pumped storage station is concrete face rockfill dam.Guided with the concept of making full use of the excavated materials from reservoir basin expansion to fill the dam and achieve balance of the earth-rock excavation and filling,reasonable dam zoning and dam construction materials shall be designed according to the requirements of dam deformation,seepage characteristics and stability of the dam in combination with the topographic conditions of dam foundation;at the construction stage,the design of dam zoning is optimized according to the actual conditions of the source of materials for saving the project investment.The calculation,monitoring in construction period,inversion analysis and monitoring results in operation period show that the total deformation of the dam is small,the stress distribution conforms to the general rules of similar projects,and the concrete face deflection and deformation of stress and joints are all within the allowable range.
