城际铁路尽头式车站信号设备布置对站场长度的影响

城际铁路地下尽头式车站受线路坡度、站场场坪以及工程投资限制,要求在满足功能及安全需求的前提下最大限度地优化站场设计长度。为配合站场专业完成优化设计,通过对动车以及应答器等信号设备工作及安全性能分析,深化研究设计规范对各项安全距离的规定,达到通过信号设备合理布置进而优化站场设计的目的。以此为出发点,计算缩短站场股道长度的理论数值,通过优化信号设备布置,缩短站场股道长度是可以实现的。

Influence of Signaling Equipment Arrangement on Station Yard Length of Dead-end Type Station on Intercity Railway

Restricted by line slope,station yard area and project investment,the dead-end type station on intercity railway has a requirement that the design length of station yard should be optimized as good as possible on the premises of meeting the function and safety demands.To cooperate the station yard discipline to do well in optimization design,the paper analyzes the service behavior and safety performance of EMU and signaling equipments like the balise,and makes a closer study on the provisions of every safe distance stipulated in design standard codes,so as to achieve the optimization of station yard design through reasonable signaling equipment arrangement.It is concluded that from this starting point,the track length of station yard can be calculated and shorten by means of optimizing the signaling equipment arrangement.
