摘　　要：以一个梁式桥为例,介绍和分析了桥梁动力荷载试验的过程。通过对测试数据进行分析,得到结构的动力指纹,有效掌握了结构的动力特性,为考察桥梁结构承载力的变化提供了依据。A dynamic-based evaluation procedure of load-carrying capacity for existing girder bridges is proposed. By analysis of the test data, dynamic signal of the bridge is acquired which show structural dynamic feature and provide the basis for researching the change of bridge bearing capacity.
