大跨桥梁结构损伤检测的研究进展

On research development of defect inspection at large-span bridge structures

通过介绍国内外大跨桥梁结构损伤识别方法的研究进展,对人工检测、振动模态检测、无损检测、概率统计方法检测四种大跨桥梁结构损伤识别方法进行了分析和总结,为我国大跨桥梁结构施工企业在大跨桥梁结构施工方面的进一步发展提供借鉴和参考。

By introducing the research development of the defect inspection at large-span bridge structures as home and abroad,the paper analyzes and sums up the defects identification methods of bridge structures,including the manual inspection,vibration models,non-destructive testing,and probabilistic method of the large-span bridges,so as to provide some reference for construction enterprises of large-span bridges in the aspect of construction.
