摘要:
为满足都市圈城际铁路公交化运营要求，需实现设计折返能力。以现状技术条件下双司机作业、单线折返为基本方案，提出基于CTCS2+ATO(中国列车运行控制系统二级结合列车自动运行)列车运行控制系统的折返间隔计算方法。研究增加折返线、优化折返作业组织对提高折返能力的效果，并进一步探讨采用两线交替折返方案及单线折返方案来实现设计折返能力的技术条件和相关数值规律。研究结果表明：在单折返线条件下，折返线作业时间阈值为64 s，可作为自动折返技术条件下折返线作业时间优化目标值；在双折返线交替折返条件下，折返线作业时间阈值为244 s，可按此制定自动折返技术调试期折返作业规程。
Abstracts:
For fulfilling MIR (metropolitan intercity railway) public transport operation requirements, building targeted turnback capacity is necessary. Taking double drivers operating with single turnback line as the basic scheme under current technical conditions, a method of calculating turnback interval based on CTCS2+ATO train operation control system is proposed. The effect of enhancing turnback capacity by adding turnback line and optimizing turnback operation organization is studied. Furthermore, it is discussed to realize targeted turnback capacity and relative numerical laws by adopting the scheme of interchangeable double turnback lines and single turnback line. Results show that, in case of single turnback line, the threshold of turnback line operation time is 64 s, which can be set as the optimized target value for turnback line operation time under automatic turnback technical conditions; in cased of interchangeable double turnback lines, the threshold is 244 s, which can be referred to for formulating turnback operation regulation during automatic turnback technical commissioning period.
