摘　　要：随着传感技术、信号采集与处理等技术的发展,桥梁结构模态参数识别方法在桥梁结构健康监测领域已经得到普遍重视。然而,将这些方法应用于实际工程中遇到了很多困难。该文基于近20a来国内外振动信息的桥梁结构模态参数识别算法的研究和应用现状,重点回顾了桥梁结构模态参数识别算法,并对有待于进一步研究的问题进行了展望。With the development of sensing technology,signal collecting and processing technologies,the modal parameter identification methods of bridge structure have been commonly used in the health monitoring field of bridge structure.However,these methods have many difficulties when used in the practical engineering.The article focuses review on the modal parameter identification methods of bridge structure according to the study and application status of modal parameter identification method of bridge structure based on the 20-year local and foreign vibration data,and expects the further study of these problems.
