摘要
为确定机场终端区最大容量保障能力,即极限容量,从终端区运行特点分析出发,综合考虑进离场航线长度、飞行速度、管制间隔等因素,构建进离场网络流模型,并以跑道Pareto容量包络线作为约束,分析进离场航线网络与跑道的耦合关系,建立基于阻塞流的机场终端区极限容量评估模型。以杭州萧山机场终端区为例,验证了模型的可行性和准确性,并借助模型分析了不同流量控制策略下终端区容量包络线的变化趋势。研究表明,随着移交间隔变大,终端区容量包线有内移的趋势,进场容量由33架次/h逐步降为25架次/h。
In order to make sure the maximum airport terminal area capacity, namely the ultimate capaci- ty,the operating characteristics of the terminal area was analyzed, considering the arrival and departure route length ,flight speed, control separation and other factors, arrival and departure network flow models was built, the runway Pareto capacity envelope as a constraint, the coupling relationship between the run- way and routes network was analyzed, the ultimate capacity evaluation model of the airport terminal area based on flow decomposition barrier was established. Taking the Hangzhou terminal area for example, the feasibility and accuracy of the model was verified, and the variation tendency of terminal area capacity en- velope was analyzed, when using different air traffic flow control measures. The results indicate that： ter- minal capacity envelope will move inside with transfer intervals become larger, the arrival capacity de- creased from 33 to 25 vehicles per hour gradually.
