摘　　要：三峡工程是一座以防洪、发电和改善航运等综合利用的特大型骨干工程。三峡工程最大下泄流量达102500m3/s;水电站总装机容量22500MW,单机容量大(700MW),装机台数多(26台),电站变幅水头大(达40m);双线五级船闸总水头高(113m),通航要求高,一线下水年通过能力达5000万t,一次需通过万吨级船队,船闸规模大且在左岸山体开挖形成;施工导截流流量大,技术复杂;混凝土工程量大,浇筑强度高等。因此,长江勘测规划设计研究院经过长期设计研究,在枢纽总布置、大坝、水电站厂房、通航建筑物、施工导流和施工总进度设计技术方面,大胆应用了一系列创新技术,成功解决了众多技术难题,提升了我国水电工程勘测设计技术水平,促进了我国的水电技术发展。The Three Gorges Project is a large-scale backbone project,including flood-control,power generation and shipping improvement.The maximum discharge reaches 102 500 m3/s and total installed capacity of hydropower station achieves 22 500 MW.Its single-machine capacity is large（700 MW）,installed sets reach 26,and the hydropower station range of water head is high（40 m）.Also,double-line five-grade ship lock of water head is high（113 m）,navigation demanding is higher,first line has the water transport ability of 50 million tons ability and 10 000-ton ships can go through at one time.Through a fleet of large scale,the left massif excavates.Large flow is formed in the river diversion and closure of construction with the complex technology,high strength,large quantities of concrete.Therefore,the Yangtze river survey design institute applied a series of technological innovation successfully through long-term planning design,layout,the dam project in hydropower plant,navigation,building construction,construction diversion and total design technology progress,and solved many technical problems.This promotes the level of hydropower engineering survey and design technology.
