摘　　要：为了推动公路车-桥耦合振动理论的发展和仿真技术的广泛应用,从公路车-桥耦合振动理论研究和应用研究2个方面系统性梳理了公路车-桥耦合振动相关领域的学术研究现况、既有研究成果、发展前景、存在的问题和对策。理论研究方面,系统总结了车-桥耦合振动研究中车-桥、桥梁、路面不平整度等参数的数学模型和车-桥耦合时变系统动力学方程的数值解法。基于调研和分析发现,经过国内外学者长期的努力,车-桥系统数值模型已经可以越来越真实地模拟实际车辆、桥梁以及路面不平整度等其他条件因素。在未来的研究中应持续改进有限元建模技术和优化数值算法,以进一步提高车-桥耦合振动仿真分析的精度和效率,扩展其应用范围。应用研究方面,以桥梁动力冲击系数、桥梁疲劳分析、桥梁结构损伤识别、桥梁振动控制、桥上行车舒适性以及桥上车辆荷载动态识别等6个问题为例,综述了车-桥耦合振动仿真技术在桥梁安全相关研究领域的应用现状,并对目前研究仍存在的局限和后续的研究方向进行了初步探讨。研究表明,车-桥耦合振动仿真技术已成为众多相关研究领域内的重要研究方法,在部分研究领域已展现了良好的应用前景。后续研究中,一方面应针对具体问题的特点改进车-桥耦合振动模型的适用性和计算精度,另一方面应针对具体研究问题进一步完善相关理论,并从工程实用性角度提出新的或改进的技术和方法。In order to promote the theoretical development of vehicle-bridge interaction（VBI）and application of VBI simulation techniques,this review systematically summarizes the state of the art,remaining gaps,and predicted trends in the research field of VBI in terms of both theory and application.From a theoretical perspective,numerical models for vehicles,bridges,and road surface roughness,as well as numerical methods for solving the time-variant dynamical system of VBI,were thoroughly examined.Following a comprehensive review,it was found that these numerical models are able to achieve increasingly realistic simulations of VBI.For future theoretical research,it is advised that finite element modeling techniques and optimized numericalmethods should be improved upon to further increase the accuracy and efficiency of VBI simulation.From an application perspective,six applications of VBI（dynamic impact factor,fatigue of highway bridges,damage detection,vibration control,ease of driving on bridges,and vehicle weight identification）are discussed to highlight the uses of VBI in research fields relating to bridge safety and serviceability.The remaining gaps in these research areas are also identified and corresponding future research is proposed.The current research demonstrates that VBI simulation has become an important tool in many relevant research fields,while its applications also show promising prospects in other related fields.For future research,the suitability and accuracy of VBI models need to be adjusted for the specific issues targeted,relevant theories need to be further developed for targeted research,and existing technologies need to be improved from the perspective of engineering practice.
