摘　　要：本文提出了列车、上承式钢板梁桥空间振动的有限单元分析模型 ,采用计算机模拟方法 ,计算了列车提速后通过 32m上承钢板梁桥的空间振动响应 ,检算该桥是否具有足够的刚度及良好的运营平稳性 ,所得结果与实测资料相符 。In the paper,one of the finite element analytical models for spatial vibration of the train and deck steel plate girder bridge system is presented.The computer simulation methods are adopted and the spatial vibration responses are calculated when the train runs through the deck steel plate girder bridges of 32m span at high speeds in order to test if the bridges have sufficient rigidity and operation stability.The results coincide with the field test data and provide reference for policy making departments.
