站坪滑行道是航班进出机位的重要活动区域，其运行顺畅性直接关系到机场的地面运行效率。针对大型机场站坪滑行道的主要运行模式进行了系统分析，以北京新机场“中心放射状”航站楼构型为研究对象，规划了3种站坪滑行道运行方案，分别为双通道单向运行、设置推出等待机位、三通道两出一进运行方案。应用Simmod仿真软件对不同站坪滑行道运行方案进行仿真模拟评估。仿真结果表明，3条站坪滑行通道两出一进运行模式的进离港航班地面延误时间最小，较之其他两种运行方案在不同航班量下离港地面延误平均减少约10%~15%。航班地面延误中：离港航班起飞等待延误占比超过50%，夹角区内延误占比约为20%；进港航班跑道穿越导致延误占比约为50%。%Apron taxiways are the important active areas for the flight power-in or push-out gate. The smooth operation of the apron is directly related to the ground operation efficiency of the airport. First, the main operating modes of the apron taxiways in large scale airport are systematically analyzed. Then, using Beijing New Airport (BNA) as the research object, three apron taxiway operational patterns are carried out, respectively dual-channel and unidirectional operation pattern (DCU), setting push-out waiting position operation pattern (SPWP), triple-channel with one-in and two-out operation pattern (TC). Finally, Simmod simulation software is operated to construct the computer simulation models for different utilization patterns of apron taxiways. The simulation result shows that the ground delay time of arrival and departure flights in TC operation mode is the least, compared with the other two kinds of operation patterns, the average reduction of the departure ground delay in different flights is about 10%~15%. Departure flights take off waiting delay accounted for more than 50%, the terminal angle area delay accounted for about 20%;arrival flights runway crossing leading to delays accounted for about 50%.
