采用风-车-桥相互作用的三维风模型，分析了青马悬索桥的动力响应和列车在湍风作用下的运行行为。该模型由空间有限元桥梁模型、由8辆27自由度4轴相同客车组成的列车模型和湍流风模型组成。由于列车运行在桥面内，脉动风力，包括抖振力和自激力，只作用于桥梁。计算了该桥的动力响应，并与台风约克的实测值进行了比较。研究了列车在不同风速下通过青马悬索桥时在不同风速下的运行性能。在此基础上，提出了保证列车在桥面上安全运行的风速门槛曲线，并据此确定了不同风速下的允许风速。计算结果表明，当平均风速达到30m/S时，青马悬索桥的轨道交通应关闭。
The dynamic responses of the Tsing Ma suspension bridge and the running behaviors of trains on the bridge under turbulent wind actions are analyzed by a three-dimensional wind-train-bridge interaction model. This model consists of a spatial finite element bridge model, a train model composed of eight 4-axle identical coaches of 27 degrees-of-freedom, and a turbulent wind model. The fluctuating wind forces, including the buffeting forces and the self-excited forces, act on the bridge only, since the train runs inside the bridge deck. The dynamic responses of the bridge are calculated and some results are compared with data measured from Typhoon York. The runnability of the train passing through the Tsing Ma suspension bridge at different speeds is researched under turbulent winds with different wind velocities. Then, the threshold curve of wind velocity for ensuring the running safety of the train in the bridge deck is proposed, from which the allowable train speed at different wind velocities can be determined. The numerical results show that rail traffic on the Tsing Ma suspension bridge should be closed as the mean wind velocity reaches 30 m/s.
