摘　　要：结构模态参数的测试与评定是工程结构检测的重要组成部分,对桥梁静力、动力评定指标进行了探讨,通过对20余座桥梁动、静载试验结果数据样本的分析,验证了动力刚度与静力刚度指标的一致性,采用模态参数可以进行桥梁结构状态的快速测试与分析。The test and assessment of structural modal parameter play an important part in engineering structure detection. This paper discussed assessment indexes of bridge static and dynamic and verified the consistency of dynamic stiffness and static stiffness through analyzing data samples from dynamic and static tests of over 20 bridges. It was concluded that quick test and analysis could be done on bridge structure state by adopting modal parameter.
