20世纪末,主跨890m的世界最大跨径斜拉桥日本多多罗大桥建成。进入21世纪后,多个国家争先开展适应越江跨海超大型工程的千米级斜拉桥的规划研究,千米级斜拉桥的结构体系、设计及施工控制核心技术成为了代表新世纪世界桥梁工程技术发展的第一制高点。经过8年多的艰苦攻坚和工程验证,“千米级斜拉桥结构体系、设计及施工控制技术研发团队”率先攻克了这一世界级重大技术难题,支撑了世界上首座突破千米的第一大跨径斜拉桥——苏通大桥的建设,实现了桥梁技术新的跨越,引领了世
The end of the 20th century, the main span 890m of the world’s largest span cable-stayed bridge in Japan completed Dolo. After entering the 21st century, a number of countries are striving to carry out the planning and research on the kilometer-class cable-stayed bridges adapted to the super-large projects across the river. The core technology of the structural system, design and construction control of kilometer-sized cable-stayed bridges has become the symbol of the new world The first high point of bridge engineering and technology development. After more than eight years of hard work and engineering verification, “kilometer-class cable-stayed bridge structural system, design and construction control technology research and development team ” took the lead in capturing this world-class major technical problems, supporting the world’s first breakthrough km The construction of the first large span cable-stayed bridge - Sutong Bridge, to achieve a new bridge technology, leading the world
