摘　　要：对于都市圈城际和市域铁路车站,其到发线有效长度计算根据线路性质,按照警冲标、出站信号机、道岔等控制条件来确定。为进一步优化缩短到发线有效长,并保证行车安全和运输效率,分析CTCS2+ATO列控系统对到发线有效长的控制因素及列控车载设备性能,结合采用的动车组列车长度,借鉴城轨交通CBTC信号系统的防护策略,提出采取列车进站停车防护区段外移的优化方式,可将车站到发线有效长从370 m缩短至270 m,进而缩短车站土建规模,节省投资;列车停准停稳后,通过采用牵引切除、触发最大常用制动、EOA点回撤等技术手段,也能提高行车效率和确保行车安全;对有关延续进路解锁关键技术以及CTCS2+ATO列控系统设备改造的技术方案进行深入研究,明确了列控系统改造设备和软件修改内容。该研究成果可为都市圈城际和市域铁路工程设计、系统研发中站场和信号专业提供理论基础。For intercity and regional railway stations in the metropolitan area,the effective length of arrival&departure track is calculated according to the nature of the line and the control conditions such as fouling post,departure signal and turnout.In order to further optimize and shorten the effective length of arrival&departure track,and to ensure traffic safety and transportation efficiency,this paper analyzes the control factors of CTCS2+ATO train control system to the effective length of arrival&departure track and the performance of train control onboard equipment.In combination with the adopted EMU length and referring to the protection strategy of CBTC signal system in urban rail transit,it puts forward an optimization mode of shifting the protection section of train stop outside,which can shorten the effective length of arrival&departure track from 370 m to 270 m,thus shortening the civil construction scale of the station and saving investment;after the train stops correctly and stably,it can also improve the driving efficiency and ensure the driving safety by adopting technical means such as traction removal,triggering the maximum service braking and EOA point retracement;the key technology of successive route release and the technical scheme of CTCS2+ATO train control system equipment renovation are deeply studied,and the contents of train control system equipment renovation and software modification are defined.The research results can provide theoretical basis for the station yard and signal discipline in the engineering design and system development of intercity and regional railways in metropolitan areas.
