车站相邻线路线间距的合理取值研究

Study on Reasonable Selection of the Midway between Adjacent Tracks inside Railway Station

研究目的:研究确定正线与到发线间设置站房柱的线间距,以及客货共线铁路车站相邻线路中间或预留电力机车接触网支柱的线间距是否应严格按6 500 mm执行的问题。研究结论:车站相邻线路线间距应综合考虑声屏障、接触网立柱、线间纵向排水槽、雨棚柱及站房柱等设施影响计算确定;对于正线与到发线间设置站房柱,最重要的是考虑柱体的安全性,设置护轮轨加护轮墙方案应是经济、合理、安全、可行的方案;客货共线铁路车站中间有或预留电力机车接触网支柱的线间距应根据线间所设信号机、采用接触网支柱形式、排水沟、机械化养护等综合计算确定。

Research purposes： The purposes of this paper are to discuss the way of determining the midway between main line and departure line and whether there is the midway between adjacent tracks in passenger and freight mixed railway stations as well as whether the midway between the OCS masts is 6500 ram. Research conclusions：The more attention should be paid to the facilities like noise barrier, OCS masts, longitudinal drain sump between lines, canopy column and station column, etc. when selecting the midway because they may affect calculation of the midway. The most important thing is the safety of column when arranging the station columns between main line and departure line, and for which installing check rail and check wall is a reasonable, safe and feasible way. For the midway between adjacent tracks in passenger and freight mixed railway station and for the midway between the OCS masts, the layout of signal machine, type of OCS masters, drain sumps, and mechanized maintenance shall be taken into account when doing calculation.
