市域(郊)铁路车站规模精细化设计研究

Research on the Fine Design of Suburban Railway Station Scale

研究目的:基于上海轨道交通市域线机场联络线项目工程实践,在既有经验和技术标准基础上,从重点影响车站规模的车站埋深、车站长度、站台层高三个方面进行深入剖析研究,总结科学合理的车站设计思路,指导大体量市域(郊)铁路地下车站精细化设计,实现缩减车站建设规模,减少工程投资,提升和完善市域(郊)铁路安全性、合理性、前瞻性、经济性等建设目标。研究结论:(1)优先选择刚性接触网,调整轨顶风道位置或采用相关措施后取消轨顶风道,可缩减车站层高;(2)车辆编组和类型直接影响车站长度,采用CBTC系统,可减少道岔至站台端部长度,进而缩减车站长度;(3)屏蔽门向站台内侧推移1.2 m的方式设计,可满足当前互联互通多车型对位,但仍需加强智慧包络性屏蔽门研发;(4)通过对建筑限界、轨顶风道、车辆选型、CTCS2系统、CBTC系统、接触网选型、站台至配线间距、智慧屏蔽门系统关键技术等技术层面细化调研分析,探索合理的车站设计方案和改善思路,减小车站工程规模,实现车站精细化设计,为今后市域(郊)铁路建设标准研究提供参考和借鉴。

Research purposes:Based on the engineering practice of Shanghai Rail Transit City Line Airport Tie Line Project,and on the basis of existing experience and technical standards,in-depth analysis and research are carried out from the three directions of station burial depth,station length,and platform floor height,which mainly affect the size of the station,to summarize scientific and reasonable train of thought for station design,guide the fine design of large-scale suburban railway underground stations,reduce the construction scale of the station,and reduce project investment,and improve the safety,rationality,forward-looking,economic and other construction goals of suburban railways.Research conclusions:(1)Give priority to rigid catenary,adjust the position of air duct at rail top or cancel the air duct at rail top after adopting relevant measures,which can reduce the floor height of the station.(2)Train formation and type directly affect the length of the station;CBTC system can reduce the length from the turnout to the end of the platform,and then reduce the length of the station.(3)The design of the way that the screen door moves 1.2 m towards the inner side of the platform can meet the current interconnection and multi-vehicle alignment.It is still necessary to strengthen the research and development of intelligent envelope platform screen door system.(4)Through detailed investigation and analysis on the technical aspects of building gauge,air duct at rail top,vehicle selection,CTCS2 system,CBTC system,OCS selection,distance from platform to wiring,key technologies of smart platform screen door system and so on,the reasonable station design scheme and improvement ideas are explored,the project scale of the station is reduced and the fine design of the station is realized,to provide reference for the future study of suburban railway construction standards.
