摘要：研究目的： 高速列车通过铁路挡风墙及在墙内交会时，挡风墙和列车的耦合空气动力响应会影响列车的运行安全与舒适性。本文基于高速列车气动性能动模型试验，对列车单车、交会通过挡风墙时的耦合空气动力响应进行测试与分析，以期得出挡风墙模型表面和列车车体表面压力波值及其变化传播规律。 研究结论： （1）单车运行时，挡风墙内、外侧测点压力波最大值、最小值和幅值随测点水平位置变化不大；而交会运行时，挡风墙内、外侧测点压力波最大值、最小值和幅值的绝对值在挡风墙中间交会处最大；（2）就挡风墙内、外侧表面压力变化而言，外侧测点压力波幅值远小于对称的内侧测点，对内、外侧测点，其压力变化幅值近似与列车车速的平方呈正比关系；（3）挡风墙内侧测点压力值随高度增加而减小，外侧测点压力值随高度增大而增加，建议挡风墙结构设计计算时主要考虑其内侧测点压力变化影响；（4）本研究结论可为高速铁路列车安全及防风工程的计算和设计提供基础。

Abstract：Research purposes： The aerodynamic response coupling between wind wall and high speed train will affect the running safety and comfort, when a train passes or two trains run each other by wind wall. The coupling aerodynamic response experiments were carried out by adopting the high speed train aerodynamic performance moving model rig in this paper. Then the pressure wave on the surface of wind wall and train, and its propagation law are gotten and analyzed.  Research conclusions： (1) The maximum, the minimum and amplitude of the pressure wave for the measuring points on the inside and outside surface of the wind wall change little when a train passes by the wind wall, and the absolute values of above data are the largest when two trains run each other at middle the wind wall. (2) For the pressure on the inside and outside surface of the wind wall, the amplitude of the pressure wave on the outside surface of the wind wall is far less than that on the inside surface, and these values are proportional to the square of the speed approximately. (3) The pressure on the inside surface of wind wall decreases with the measuring point height increasing, and the pressure on the outside surface of wind wall increases with the measuring point height increasing. Therefore, the pressure change inside surface of the wall should be mainly taken into account when the wind wall structure design calculation is carried out. (4) The research results can provide the basis for the high speed train running safety and wind resistance engineering calculation and design. 
