兰州至中川城际铁路折返站站型布置研究

摘要

There are mainly several intermediate stations along the Lanzhou - Zhongchuan Intercity Railway in which the construction standard is high and the investment is large. To meet the requirements of short-distance passenger transport, the turning-back trains shall be organized between two intermediate stations. In this paper, the layout of station type of intermediate turning-back station in intercity railway are discussed. To general intermediate turning-back stations, especially to the bridge type or underground station, additional receiving-departure track used mainly for turning-back operation should be set at the direction of trains' arrival so as to achieve the turning-back of trains at the station when the turning-back operations are less. With this method, not only the transport requirements can be met but also the project investment can be saved.%兰州至中川城际铁路建设标准高、投资大,全线以中间站为主.为满足输送短途客流需要,需在两中间站间组织列车折返.因此,在进行折返站的站型布置时,既要满足运输需求,又要考虑工程投资的规模.针对城际铁路中间折返站的站型布置进行了研究探讨.一般中间折返站,尤其是桥式或地下站,当折返作业较少时,可在折返列车到达方向增设主要用于办理折返作业的到发线,再通过咽喉区道岔布置实现车站列车折返.既可满足运输要求,又可节约工程投资.
