摘　　要：鉴于提高强风环境下跨海桥梁的通行能力是保障桥梁通行安全和通行效率的关键,而采用现有限速或限行的桥梁通行管理模式,不能适应未来智能交通发展的需要,本文中以厢式货车和轿车为研究对象,提出了一种强风环境下跨海桥梁行车安全评价与管控方法,研究了“风-车-桥”交互气动作用关系及其对汽车侧风稳定性的影响规律,利用强风作用下的汽车动态响应,开展了风速、车速和路面等多因素联合定量评价工作,最后对不同工况下跨海桥梁安全行车的行车组织和行车速度管控方法提出建议。In view of that the traffic capacity of cross-sea bridge under strong wind environment is the key to ensuring the traffic safety and efficiency of bridges,and the existing bridge traffic management mode of adopting speed limit or traffic restriction can not meet the requirements of the development of intelligent transportation in the future,taking van trucks and cars as the research objects,an evaluation and management method of the vehicle driving safety on cross-sea bridge under strong wind environment is proposed in this paper.The interaction of aerodynamic relationship of"wind-vehicle-bridge"and its influence on vehicle crosswind stability are studied and the quantitative co-evaluation on the multi-factors of wind speed,vehicle speed and road surface etc.are conducted by using vehicle dynamic responses under the action of strong wind.Finally,some suggestions on the vehicle driving organization and driving speed control regulation related to driving safety on cross-sea bridge under different conditions are put forward.
