摘　　要：近年来,基于模态参数的损伤识别方法发展十分迅速。结构在使用过程中会受到自身因素和外界因素影响,必然会导致结构发生损伤,影响其正常使用功能,严重时引发倒塌等事故。因此,对结构进行损伤识别具有十分重要的意义。文中主要介绍了损伤识别领域常见的几种模态参数,并总结归纳各参数的优势和不足,并对有待进一步研究的问题进行了展望,为结构健康检测领域的研究和应用提供参考。In recent years,damage identification methods based on modal parameters have developed rapidly.The structure will be affected by its own and external factors during service stage,which inevitably leads to damage to the structure,affecting its normal use function,and it would cause accidents such as collapse in severe cases.There⁃fore,damage identification of structures is of great significance.This article mainly introduces several common mod⁃al parameters in the field of damage identification,and summarizes the advantages and disadvantages of each param⁃eter.Finally,prospects are made for the issues that need further research,providing the reference for research and application in the field of structural health detection.
