摘要
正交异性板及铺装结构体系疲劳问题一直是难题,通过综合对比分析国内外正交异性板足尺结构研究现状,总结钢桥面系足尺疲劳试验能够有效、准确、快速反映结构真实力学特征,验证疲劳损伤发展规律和长期耐久性,可为我国长大桥梁正交异形钢桥面板及铺装结构体系疲劳研究和设计提供了科学依据和理论参考。
The fatigue problem of orthotropic slab and pavement structure system has always been a world-class problem.Through comprehensive comparative analysis of the research status of orthotropic slab full-scale structure at home and abroad,it is concluded that the full-scale fatigue test of steel deck system can effectively,accurately and quickly reflect the real mechanical characteristics of the structure and verify the fatigue damage development law and long-term durability.It provides scientific basis and theoretical reference for fatigue research and design of orthogonal special-shaped steel deck and pavement structure system of long and large bridges in China.
