摘　　要：随着经济的快速发展,结构损伤识别作为桥梁健康监测的核心也得到了迅猛地发展。为了全面总结现有桥梁结构损伤的识别方法,从基于结构响应类型的损伤识别方法、基于分析过程的损伤识别方法和结构智能损伤识别方法三个层面进行了详尽的剖析与总结,理清了各种结构损伤识别方法的脉络关系和技术演变过程。通过系统化分析,汇总了上述三大类损伤识别方法的主流算法,分析了各算法的优势与不足,最终对桥梁结构损伤研究领域未来的研究方向与走势进行了展望。With the rapid development of economy, the structural damage identification as the core of bridge health monitoring has been developed rapidly. In order to comprehensively summarize the exiting identification methods of bridge structure damage, the detailed analysis and summary are carried out from three levels of the damage identification methods based on the structural response types, the analysis of process and the structure intelligence to clarify the relationship of various structural damage identification methods and to ravel out the technical evolution processes. Through the systematic analysis, the mainstream algorithms of the above three types of damage identification methods are summarized, and the advantages and disadvantages of each algorithm are analyzed. Finally, the future research direction and trend of bridge structural damage research are prospected.
