摘　　要：相比于机场一起一降的运行模式,近距平行跑道的相关平行进近运行模式可以最大限度地提升跑道容量。根据尾流在大气中各个阶段的运动特性,得到了以时间为变量的尾流水平侧移距离数学模型。应用Matlab仿真软件得到了侧风及地面效应影响情况下的上海虹桥国际机场实行近距平行跑道相关平行进近的侧向尾流危险区域图,并分析得到了后机不受到前机尾流影响情况下两机需保持26.9 s的最大尾流时间间隔。利用尾流危险区域的特点,可缩短尾流时间间隔,从而大幅度提高机场容量。Compare with the operation mode of one arrival and one departure, the relevant parallel ap- proach mode of closely spaced parallel runways can improve the runway capacity as more as possible. Ac cording to different movement characteristics of the vortex wakes, a reliable computational method for pre dicting the lateral separation distance has been discussed. Finally, by using the Matlab, a lateral vortex hazardous region diagram for Shanghai Hongqiao international airport has been obtained with the relevant parallel approach mode. It is concluded that the most conservative time span of the vortex wakes between two aircraft is 26. 9s for avoiding the vortex spreading. Taking advantage of the characteristics of the vortex hazardous region, we can reduce the vortex time interval and improve the airport capacity.
