摘　　要：对齐齐哈尔嫩江公路大桥东江桥模型的动态特性进行了模态参数识别，得到了大桥模型的模态参数。通过动力相似原理换算，预示了原型的模态参数．为原桥的动态特性提供了试验数据。可供有关桥梁结构模型试验参考。This paper obtained model parameters of Dongjiang bridge model of road bridge over Nenjiang river in Qiqihaer by model parameter identification of dynamic properties.It also estimates model parmeters of real bridge by convertion according to resemble theory, and gave test data of dynamic properties of real bridge.It could be referenced while dynamic tests of relative bridge structures were done.
