摘要
流线型扁平钢箱梁作为斜拉桥的加劲梁具有良好的力学和气动性能。以福州市琅岐闽江大桥为例,简要介绍扁平斜拉桥钢箱梁结构构造设计、立面线型的实现、抗风震措施和施工过程中的临时约束设计,以丰富扁平钢箱加劲梁在桥梁设计领域中的应用经验。
Flat steel box girder has good mechanical and aerodynamic performance as the stiffening girder of cable- stayed bridge. This text introduced briefly flat steel box girder structure design of cable-stayed bridge, the realization of the facade form, wind and seismic measures and temporary constraint in the process of construction ,to rich application experience in the field of flat steel box stiffening girder.
