摘要
列车追踪间隔时间是影响高速铁路通过能力的关键因素。在影响列车追踪间隔时间大小的因素中,车站到发线运用对列车追踪间隔时间有重要影响。本文以京沪高速铁路关键节点——虹桥站为研究背景,分析一次解锁和分段解锁条件下到发线运用对列车到达追踪和出发追踪间隔的影响机理;基于CTCS-3列控系统技术特点及动车组列车牵引计算原理,对虹桥站不同到发线运用方案下的列车到达和出发追踪间隔时间进行计算分析。结果表明,到发线运用通过影响列车在车站的走行距离和进路解锁时机进而影响列车到达和出发追踪间隔时间。采用分段解锁条能够有效压缩列车追踪间隔时间,且其效果与到发线运用方式有关。
Train headway is a key factor affecting the transport capacity of high-speed railway.Utilization of arrival-departure track has an important impact on the train headway.Taking Hongqiao Station,the key node of Beijing Shanghai high-speed railway as the research background,this paper analyzes the influence mechanism of arrival departure track operation on train arrival tracking and departure headways under the condition of one-time unlocking and sectional unlocking;based on the technical characteristics of CTCS-3 Train Control System and the traction calculation principle of EMUs,the train arrival and departure headways under different application schemes of arrival-departure tracks at Hongqiao Station are analyzed calculation and analysis are carried out.The results show that the application of arrival departure track affects the train running distance at the station and the time of route release,and then affects the train arrival and departure headways.The section unlocking bar can effectively reduce the train headways,and its effect is related to the utilization of arrival-departure track.
