上海市域铁路车站到发线有效长度设计优化方案研究

Research on the Scheme of Optimizing the Effective Length of Station Receiving-departure Track in Shanghai Suburban Railway

通过分析上海市域铁路线网运用动车组选型和运输服务规划与干线铁路的差异,对采用满足上海市域铁路运输需求的CTCS2+ATO系统的车站到发线有效长度进行优化设计。调研统型后的上海市域铁路动车组参数和多个列控车载设备厂家在实际工程应用中的ATP控车曲线数据,对车站站台长度、ATP制动安全距离等数据进行分析,对自动驾驶停车精度余量开展仿真测试,考虑停车后ATP的允许速度、停站运行时间等因素,自动驾驶停车精度余量确定为15 m。优化后车站到发线有效长度为321 m,与上海机场联络线工程相比,车站到发线有效长度可缩短79 m。本研究成果应用在上海市域铁路线网后期工程,将有效降低工程造价,提高运输效率,具有显著的经济效益和社会效益。

By analyzing the difference between the EMU selection and transportation service planning of Shanghai suburban railway network and trunk railway,this paper optimizes the effective length of station receiving-departure track by using CTCS2+ATO system meeting the transportation needs of Shanghai suburban railway.This paper investigates parameters of Shanghai suburban railway EMU after unification and the ATP control curve data of several train control onboard equipment manufacturers in practical engineering applications,analyzes the data such as station platform length and ATP braking safe distance,and stimulates the automatic driving parking accuracy margin.Considering the allowable speed of ATP after parking and stop running time,the automatic driving parking accuracy margin is determined to be 15m.After optimization,the effective length of the station receiving-departure track is 321 m,which can be shortened by 79 m compared with the Shanghai Airport Link.The research results can effectively reduce the project cost,improve the transportation efficiency,and have remarkable economic and social benefits when applied in the later stage of Shanghai suburban railway network projects.
