| Abstract: |
Quanzhou Bay Railway Bridge is the key component of the Fuzhou-Xiamen High-Speed Railway with the design speed of 350 km/h. The total length of 20.3 km is the greatest among the sea- crossing high-speed railway bridges in the world. The main structure over the main navigation channel is a steel-concrete composite cable-stayed bridge with the span arrangement of（ 70+130+400+130+70）m. The main girder adopts a closed and streamlined box section. In the past decades, the sea-crossing railway cable-stayed bridges mostly adopted steel truss girder. Quanzhou Bay Railway Bridge is the first railway bridge adopting the steel-concrete composite box girder cable-stayed bridge type in china and the longest-span sea-crossing high- speed railway bridge in the world. In this paper, the structural design and construction method for this bridge are presented. |
