摘      要：The dam of Three Gorges Project is characterized by large flood discharge capacity,more outlets,complicated flood discharge and energy dissipation structure,and the stability of the bank powerhouse dam foundation is endangered by large gentle-dip structural plane of the bedrock due to the deep excavation of powerhouse at the *** the dam body concrete,the durability requirement is high and the temperature control and crack prevention are *** practical experience which could be used for reference in the design and construction of asphalt concrete core wall for Maopingxi protective earth-rock dam is *** power station operates with high water head and large head *** type selection of penstock and intake as well as the embedding way of spiral case are complicated in technique,and the tailrace tunnel with sloping ceiling of underground power plant is arranged instead of traditional tailrace surge *** the double-line five-step ship-lock,the design of fully lined ship-lock,high head delivery system and large-sized miter gates and hoists is very challenging due to high operation head,complicated delivery conditions and building in deep excavated *** preferred solutions,optimal schemes and technical measures for various structures,as well as the innovation achievements proved by practice are highlighted.
