| 摘 要： | 相比传统的两片主桁的截面形式,采用三片主桁截面形式的桥梁力学性能和空间稳定性更好。根据列车桥梁时变系统的分析理论,分别建立列车和桥梁动力分析的有限元模型,采用计算机模拟的方法,研究列车以不同车速通过三主桁拱桥时车桥耦合系统的空间振动响应。所得结果可供设计参考。

| Abstract: | According to the theory of train-bridge time dependent system, the finite element models for the dynamic analysis of train and bridge are established respectively. By computer simulation, it studies the spatial vibration response of coupled system when trains run through the three principle trusses arch bridge at different speeds. The results provide a reference for design. |

| Keywords: | three principle trusses arch bridge train vibration response |
