摘要
抗风稳定和巨大的建设费用是建设中跨超过2 000 m的超大跨度悬索桥必须首先解决的重大问题。根据本世纪日本跨越海峡、海湾长大桥梁规划中超大跨度悬索桥方案的研究结果,介绍了研究方案的桥面宽度、加劲梁断面形式、气动措施及其相应的抗风性能。
The wind-resistant stability and the enormous construction cost are the significant problems that must be firstly resolved before construction of a suspension bridge with a very long central span longer than 2 000 m. In accordance with the research findings of the proposed very long span suspension bridges planned for a number of the straits-crossing and bay-crossing major bridges in Japan in this century, this paper introduces the deck width, type of cross section of the stiffening girder, aerodynamic measures and the corresponding wind-resistant performance of a proposed bridge.
