摘要
介绍了用于高速铁路桥梁动力影响分析的车—桥耦合振动计算程序，并通过比例为１∶１０的车—桥模型试验验证了上述程序。该程序的计算结果符合模型试验的实测结果，适用于高速铁路中小跨度桥梁的竖向振动分析。
This paper presents a dynamical analytical procedure for high speed railway bridges using the theory of train-bridge coupling vibration. The procedure has been verified by the model test of train and bridge. The scale of the model is one-tenth. The numerical results agree to the results of the model test. The procedure is suitable to be used in vertical vibration analysis for moderate or short span bridges in high speed railways.
