基于控制技术缩短客专车站股道有效长的研究

Research on the Shortening Effective Length of Track for Passenger Dedicated Line Stations Based on Control Technology

研究目的:车站股道有效长是铁路主要设计标准之一,直接影响工程投资、土地资源利用及车站选址等。本文以客运专线车站为背景,运用列车运行控制原理及现行铁路运营安全规则,研究探索进一步缩短股道有效长的可行性和方法。研究结论:(1)客运专线车站股道有效长与列车编组长度、列控系统安全距离、出站应答器至出站信号机距离、有无折返作业等有关;(2)客运专线车站股道有效长与运营安全要求有关,本研究基于不考虑设置过走防护区以及完整的紧急防护区;(3)在不考虑设置过走防护区和完整紧急防护区的前提下,通过外移出站信号机至警冲标5 m,调整出站应答器位置等措施,可以进一步缩短客运专线铁路车站股道有效长约100 m;(4)对于运输不太繁忙的客运专线,可以采用设置接车进路延续进路的方案,在缩短股道有效长后保持一定的过走防护能力;(5)本研究结论可为优化客运专线铁路车站股道有效长设计标准提供参考或借鉴。

Research purposes： The effective length of station track is one of the main design standards, which directly affects the project investment, land resource utilization and station location. Under the background of passenger dedicated line （PDL） station, the paper applies the train operation control theory and current railway operation safety rules, and finally proposes the feasibility and methods for further shortening the effective length of track. Research conclusions： （ 1 ） The effective length of track for PDL stations is related to the length of train formation, the safety distance of train operation control system, the distance from the starting bafise to the starting signal, and the presence or absence of turnaround operations. （2） The effective length of track for PDL stations is related to the operation safety requirements. This research is based on the no set - up of overlap and the complete emergency protection zone. （3） Under the premise of no set - up of overlap and complete emergency protection zone, the effective length of track for PDL stations can further shorten about 100 m by removing the starting signal from fouling post 5 m and adjusting starting balise position. （4） For the less busy PDLs, the solution of setting receiving -route successive route can be adopted to keep overlap capability in the case of shortening the length of track. （5） The research conclusions can be used as reference for optimizing the effective length design standards for PDL stations.
