三峡工程若干关键科学技术问题

Key science and technical problems of Three Gorges project

长江三峡水利枢纽工程是治理长江水患、开发长江水能资源的关键性骨干工程,是目前世界上规模最大的水利水电工程。主体工程建设历经16年,在广大科技工作者和工程建设者的共同努力下,工程在电站大型钢衬钢筋混凝土压力管道和蜗壳埋入技术、泥沙技术、大跨度地下厂房开挖技术、大型升船机研究、巨型水轮发电机组制造与安装技术、大型多级船闸建设技术等诸多关键科学技术问题上取得了重大突破,极大的推动了世界水电建设技术发展。

Three Gorges hydropower, the biggest hydropower project in the world at present, is a backbone project for flood control and water power development of Yangtze River. The construction period of main works is 6 years, Under the close collaboration and persisting efforts of scientists, engineers and project builders, solutions and breakthroughs have been achieved for many key technologies, such as the embedding of large-scale steel-lined reinforced concrete penstocks and spiral cases of the power station, the sediment technology, the excavation of largespan underground powerhouses, manufacturing and installation of huge-size water turbine generators, the design and construction of large-size ship lift, the building of large-scale multi-level ship lock system. This greatly promotes the hydropower development in the world.
