城际铁路尽头式折返线信号设备布置的探讨

城际铁路尽头式折返车站的站前设计过程中,为减少地下车站隧道的设置长度,控制和优化工程建设投资,将城际铁路尽头式折返站的折返线路长度控制在较小范围,难以满足站后专业的信号设备布置要求。通过动车组的制动相关参数、地面控车设备的相关参数,结合现有的相关技术条件,采用匀变速直线运动速度与加速度和位移的关系、车载ATP的相关逻辑等方法,研究城际铁路尽头式折返线信号机、应答器、车挡、轨道电路等信号设备的技术标准,分析城际铁路尽头式折返线信号设备布置的问题,结合工程实践提出解决方案。

Discussion on Arrangement of Signal Equipment for End Type Turn-back Tack of Intercity Railway

In the pre-station design process of the intercity railway terminal-type turnback station,the length of the turnback line of the intercity railway terminal-type turnback station is controlled in a small range in order to reduce the tunnel length of the underground station and to control and optimize the construction investment,so that it is diffi cult to meet the requirements of professional signal equipment layout after the station.By bullet train brake related parameters,the ground handling equipment related parameters,combined with the existing relevant technical conditions,by using uniform variable linear motion velocity and acceleration and displacement relationship,on-board ATP related logic method,type turn line at the end of the inter-city railway signal,transponder,car blocking,track circuit signal equipment such as technical standards,analyses the layout type turn line at the end of the inter-city railway signal equipment problems,combining with engineering practice put forward the solution.This paper analyzes the type turn line at the end of the Inter-city railway signal equipment layout problem,and it gives solution based on engineering practice.
