摘要
结合佛陈大桥主桥大跨度钢箱连续梁设计情况,对正交异性钢桥面板疲劳问题进行分析,提出了优化结构设计及采用超高韧性混凝土桥面铺装来改善疲劳的对策措施,并以足尺试验验证改善效果。
Combined with the design of long-span steel box continuous beam of the main bridge for Fochen Bridge, this paper analyzes the fatigue problems of orthotropic steel deck slab, puts forward the countermeasures for the optimization of structural design and the use of ultrahigh ductile concrete deck pavement to improve the fatigue, and verifies the improvement effect by the full-scale experiment.
