京津城际延伸线开行市郊列车方案研究

Study on the Suburban Railway Scheme of Extension Line in Beijing-Tianjin Inter-city Railway

本文通过分析京津城际延伸线的实际背景,提出京津城际延伸线列车运行存在的问题,并制定相应的改造原则与目标。根据金山铁路改建服务市郊出行市域快速铁路的运输组织方式和运营管理模式,提出利用区段富余能力开行市郊列车、区段独立开行市郊列车委托北京局运营、区段独立开行市郊列车委托轨道交通集团运营3种典型市郊列车开行方案,通过对工程投资额、运营成本、运输组织灵活性、线路利用率等方面的对比分析,推荐方案I为京津城际延伸线的开行方案,此方案可以更好的满足天津市区与塘沽、滨海间的客流需求,在加强天津市承接首都功能的同时,可以进一步发挥交通引领城市发展的作用,为城市发展带来巨大的社会效益。

Based on the analysis of the actual background of Beijing-Tianjin intercity extension line, the problems which exist in the operation of the intercity extension line are proposed, and the corresponding transform principles and objectives are formulated in the paper. According to the transportation organization mode and operation management mode of Jinshan railway which is reconstructed as city express railway to serve suburbs, 3 typical suburban train operation schemes are proposed, namely operating suburban trains by using the section surplus capacity, operating suburban trains independently which is commissioned to the Beijing Railway Bureau, and operating suburban trains independently which is commissioned to the Rail Transit Group. With the comparative analysis of project investment, operating cost, the flexibility of transport organization, the utilization rate of railway and so on, we propose scheme I as the operation scheme of Beijing-Tianjin intercity extension line. The research shows that the Scheme I can better meet the passenger demand between Tianjin urban area and Tanggu, Binhai New Area, further play the role of transportation in leading city development with strengthening the function of Tianjin to undertake the capital, and bring huge social benefits for the development of the city.
