摘　　要：自进入21世纪,我国公路与铁路交通在高速化与重载化得到了巨大的发展,而桥梁也朝着轻质、大跨迈进,车-桥结构的动力问题越来越突出,车-桥耦合振动的研究因此获得了许多的关注。在回顾了近20年中国在车桥耦合问题研究的基础上,总结了车-桥耦合振动研究的车辆模型、桥梁模型及数值计算方法,并针对关于地震荷载、风荷载、不平整度和共振等4个方面的车-桥耦合振动研究内容做了系统介绍。并对车-桥耦合需要进一步研究的问题进行了探讨,可对今后车-桥耦合问题的研究提供一定的参考。Since entering the 21st century,China s highway and railway transportation have been greatly developed in terms of higher speed and heavier load.As more and more bridges have light weight and long spans,and the dynamic problem of vehicle-bridge structure is more and more prominent.Therefore,attentions have been focused on the research of vehicle-bridge coupling vibration.Based on the review of the research on vehicle-bridge coupling in recent 20 years in China,the vehicle model,bridge model and numerical calculation method of vehicle-bridge coupling vibration were summarized.And the research contents of vehicle-bridge coupling vibration in four aspects of earthquake load,wind load,unevenness and resonance were introduced systematically.Finally,some issues of vehicle-bridge coupling were suggested to be further studied,which could provide some reference for the future research of vehicle-bridge coupling.
