与市域快轨贯通运营的市域(郊)铁路技术标准研究

Research on Technical Standards for Urban Railways Connected with Urban Fast Rail Operations

市域(郊)铁路与市域快轨贯通运营时,对两者的系统制式和技术标准产生深远影响,如何确定合理的技术标准是前期研究的重点和难点。本文以市域(郊)铁路苏虞张线为例,从客流需求、资源共享、与系统能力适应性分析苏虞张线与市域快轨10号线的互联互通方式,提出采用分段运输、兼顾贯通的方式互联互通。基于功能定位及客流需求,统筹与10号线构建南北向市域快线骨架,多维度综合比选速度目标值,从各层级网络统筹、各专业配套投资及车辆全寿命周期成本角度进行系统性综合经济技术比选车辆选型,推荐设计速度采用160 km/h,车辆采用市域A型车,建议10号线采用交流25 kV供电制式,与苏虞张线供电制式保持一致,确保两条线路贯通运营的可靠性和灵活性。

The connection and operation of urban railways and urban express railways have a profound impact on the system format and technical standards of both.How to determine reasonable technical standards is the focus and difficulty of preliminary research.This article takes the Suyuzhang Line of the urban railway as an example to analyze the interconnection and interworking methods between the Suyuzhang Line and the urban fast rail Line 10 from the perspectives of passenger flow demand,resource sharing,adaptability to system capacity.It proposes to adopt segmented transportation and consider connectivity.Based on functional positioning and passenger flow requirements,we will coordinate with Line 10 to build a north-south urban expressway framework,and comprehensively compare and select speed target values from multiple dimensions.We will conduct a systematic and comprehensive economic and technological comparison and selection of vehicles from the perspectives of network coordination at all levels,supporting investment in various specialties,and vehicle life cycle cost.It is recommended to use a design speed of 160 km/h,and the vehicles will use urban A-type vehicles.It is recommended that Line 10 adopt an AC 25 kV power supply system,maintain consistency with the power supply system of the Suyuzhang Line to ensure the reliability and flexibility of the connection and operation of the two lines.
