城际铁路到发线有效长研究

根据到发线有效长的原始定义,提出影响城际铁路到发线有效长的4个组成因素———列车长度、停车余量、安全防护距离、警冲标至绝缘节的距离。针对这4项影响因素逐项进行详细分析,并结合城际铁路设计实际在有到发线中间站、无到发线中间站及尽头式终点站3种车站布置形式下进行实例计算,初步得到了城际铁路到发线在不同组织模式下的有效长度,得出了城际铁路中间站不同布置形式下的到发线有效长。。

Research on Effective Length of Receiving-Departure Track of Intercity Railway

According to original definition of the effective length of receiving-departure track,this paper pointed out four influence factors for the effective length of receiving-departure track in an intercity railway: the length of the train,the spare capacity of the parking,the distance for safety protection,the distance between caution sign and insulation joint.Then,in allusion to the four influence factors,the detailed analysis was conducted in this paper.And then,in combination with actual design project,three kinds of station arrangement were calculated respectively,including the station arrangements with or without the intermediate station of receiving-departure track,or with dead-end destination station.As a result,the effective lengths of receiving-departure track under different organizations were obtained initially in this paper.
