无锡地铁2号线站前折返信号仿真分析与改进

Simulated Analysis and Improvement of Turnaround Signal before Entering Station on Wuxi Metro Line 2

以无锡地铁2号线安镇站为例,通过信号系统仿真,对2种传统站前折返方式进行了详细分析,发现其折返能力不能满足运营间隔120 s的设计要求,未来将对线路运输能力产生影响。为此,提出了2种改进该站折返能力的方案,即更换道岔和采用新的折返运营方式,可供运营单位参考。

Taking Anzhen station on Wuxi metro line 2 as an example, through simulation of signal system, the paper makes detailed analysis of two traditional modes of turnaround operation before entering station. It is found that turnaround capacity fails to meet design requirements of 120 s operational intervals, having an impact on future rail transport capacity. For this purpose, the paper puts forward two schemes for improving the turnaround capability for station, i.e. to replace the turnouts and use new way of turnaround operation.
