摘　　要：为保障终端空域正常运行,对终端空域拥堵演变机理进行研究。将拥堵分为自身结构致因和外部因素致因两类,建立了拥堵形成与消散的分析模型;依据交通流演化的特征指标及Greenshields理论建立了拥堵机理尖点突变分析模型。以成都终端空域为研究对象,利用AirTOp软件生成仿真运行数据,验证了模型有效性。结果表明,所设计模型可有效描述拥堵演化的宏观过程,通过航段当量流量、密度及波速的变化,可有效对拥堵演化的机理进行分析。The study of congestion evolution mechanism in terminal airspace is a vital measure to ensure the normal operation of terminal airspace.This paper divides congestion into two categories:its own structural causes and external causes,and establishes a corresponding analytical model for congestion formation and dissipation.Based on the characteristic indexes of traffic flow evolution and Greenshields theory,the cusp catastrophe analysis model for congestion mechanism is established.In order to verify the validity of the model,this study takes the Chengdu terminal airspace as the object and uses AirTOp software to generate simulation operation data.The results show that the designed model can effectively describe the macroscopic process of congestion evolution,and the mechanism of congestion evolution can be effectively analyzed through the changes of equivalent flow,density and wave speed in the segment.
