桥梁结构损伤识别研究现状与展望

Research status and prospect of bridge structure damage identification

为了更全面地总结现有桥梁结构损伤识别方法,深入开展桥梁结构损伤识别研究提供系统有效的信息,对现有结构损伤识别方法从数据来源和分析方法2大方面进行了总结归纳,理清了各种结构损伤识别方法的脉络关系及技术演变过程,主要包括静、动力损伤识别方法和反演与模式识别方法2大类,对基于小波的损伤识别方法作了重点剖析;分析了现有结构损伤识别方法的应用现状、优点和不足,总结了结构损伤识别领域的研究热点。针对桥梁结构的特点,指出建立基于施工监控、荷载试验、健康监测和人工巡检四位一体的多体系损伤识别方法是桥梁结构损伤识别的发展方向。

To have a comprehensive summary of existing methods for damage identification of bridge so as to provide systematic and effective information, from aspects of data sources and ana lytical methods, the existing methods of damage identification were summarized to sort out the technical evolution of the various damage identification methods including the static and dynamic damage identification and inversion and pattern recognition methods, among which the wavelet damage identification methods were expounded in details. Then, the application status, advanta ges and disadvantages of various methods were analyzed, and the improvement ideas and methods were summarized. Finally, establishment of four-in-one multi-system damage identification meth od was proposed based on construetion monitoring, load tests, health monitoring and artificial pa trol, which is the development trend of the bridge structure damage identification. 6 figs, 60 refs
