本文阐述了城市轨道交通网络化运营的概念,分析了网络化运营的物理环境及其客流基本特征,提出了城市轨道交通公益性的3个重要标志.通过对国内外城市轨道交通网络化运营理论与实践的评述,提出了城市轨道交通网络化运营的主要目标;指出了网络化运营管理面临的三大主要问题,即断面负荷均衡、车站负荷均衡及换乘衔接改善.基于既有的多交路、多编组、快慢车及过轨运营等主要网络化运营技术,分析不同方法的技术特点及其对出行者的影响,提出了不同方法的适用性.最后,从不同角度分析了不同网络化运营技术实施过程对乘客与企业的具体效果,提出了促进我国城市轨道交通网络化技术应用的建议.%This paper gives the definition of urban rail network operation, and analyzes its physical environment and also characteristics of passenger flows. Three symbols have been marked as the common welfare of urban rail transit. By reviewing the theory and practice of network operations around the world, it advances the targets of train operations under rail network environment. With the environment, three problems such as sectional loadings, station loadings and interchange design are faced by working out train schemes. Based on the existing network operational technologies including multiple turn-backs, variable train lengths, skip-top operation and train over-tracking, it analyzes the characteristics of the technologies and their impact on passenger journeys, and advances the applicability of the technologies respect to practical network conditions. Finally, it elaborates the possible impacts of the application of the technologies on passengers and operators while their implementation in practice, points out the suggestions for prompting the application of urban rail network operational technologies in China cities.
