基于运行容量仿真的近距平行双跑道设计快速评估研究

Research on Simulation Evaluation of Operation Capacity of Closed Spaced Parallel Runway Design

受空间资源及地理位置限制,近距平行双跑道设计成为多数目前机场增加容量最直接的方式之一,但其主要采用隔离运行模式,虽与单跑道运行相比容量有所提升,但保留了较高的安全裕度,使得平行双跑道的利用率不高,容量提升效果不明显。因此,需在预研及设计阶段对容量进行提前评估,得到性能最优化的机场设计构型。市场上对民用机场运行效率的成熟评估软件主要为国外软件商,自主研制的软件工具稀缺,难以在设计初期以定量化的手段对设计进行最直观的评估。所以本文将结合计算机仿真技术,基于标准近距平行双跑道设计布局,对飞行全过程进行数学建模及系统逻辑仿真,搭建起单、双跑道侧机场跑道容量仿真评估技术路径,实现双跑道进、离场的参数可调实时容量计算原型系统开发,同时针对不同错列距离设计参数开展容量仿真,辅助开展最佳设计决策与成果评估。

Due to the limitation of space resources and geographical location,the design of closed spaced parallel runways has become one of the most direct ways to increase the capacity of airports at present.Although the capacity has been improved compared with the single runway operation,it retains a higher safety margin because of its isolated operation mode,which leads to the low utilization rate of parallel double runways and the unknown effect of capacity improvement.The capacity needs to be evaluated in advance at the pre-research and design stage to obtain the airport design with optimal performance.Now the mature software for the operational efficiency evaluation of civil airports on the market is mainly foreign software vendors,and the self-developed tools are scarce,which makes it difficult to conduct the most intuitive evaluation of the design by quantitative means at the early stage of design.Therefore,based on the design layout of standard close-range parallel double runways,this paper applies computer simulation technology to carry out mathematical modeling and system logic simulation for the whole flight process.What’s more,this paper builds the technical path of runway capacity simulation and evaluation for single and double runways to realize the development of real-time capacity calculation prototype system,which can adjust parameters freely for the approach and departure of closed spaced parallel runways,accomplishes capacity simulation for different staggered distance design parameters,and assists in the best design decision and result evaluation.
