摘　　要：介绍了桥梁结构健康监测的一些实际应用 ,阐述了结构损伤识别的现状 ,并对有关损伤诊断的一些方法进行了评价 .重点论述了曲率模态分析的基本理论 ,探讨了曲率模态在结构损伤检测中的应用 。In this paper, several practical implementations of health monitoring for bridges are reviewed. Actuality of damage identification for structures is expatiated and comments are made on the methods of them. Considering that curvature mode shape can identificate the damage of structures and locate it, the theoretical basis of curvature modal analysis is discussed emphatically in the paper. The applications of curvature modal analysis in damage detection are probed into. Finally, several problems which should be regarded in the actual work of damage identification for structures are put forward and conclusions are given.
