在既有横流理论基础上，通过理论建模得到站台活塞风与送风射流动态耦合速度场数学模型，该模型得到了液体缩尺模型试验的验证，两者的偏差在10％以内。由理论解析求解进一步分析得到这两股气流耦合轴心轨迹分3个阶段变化；并得到耦合射流轨迹与水平面夹角、轴心速度等特征参数的动态及典型时刻变化特性。

Based on the existing cross-flow theory,develops the mathematical model of coupled velocity field of air jet and piston wind,which is validated by the liquid scale model test with a deviation of 10%.The analytic solution shows that the axis trajectory of coupled jets of the two airstreams can be divided into three phases.Obtains the variation of the angle between the trajectory and the horizontal plane,as well as the variation feature of axis velocity and other characteristic parameters during both the dynamic process and the typical period.
