高速铁路动车走行线通过信号机设置及显示方案探讨

Research on the Scheme of Setting and Displaying Mode of Passing Signal on EMU Running Track of High-Speed Railway

动车走行线是动车组进、出动车运用所的必经之路,确保动车走行线的通过能力,对于保证高速铁路的正常运营秩序意义重大。以东北某高速铁路动车走行线为例,针对存在的动车走行线通过信号机设置和显示关系的不同见解,通过对相关规范条文的深入分析,结合具体工程应用实例,提出能够更好发挥动车走行线通过能力的通过信号机设置及信号显示方案,并提出了进一步提高动车走行线通过能力途径的建议。

The running track is the only way for electric multiple unit （ EMU ） getting in or out of the EMU servicing depot, therefore, ensuring the passing ability of the EMU running track will play an important role for ensuring the normal operation of high-speed railway. This paper, taking the EMU running track on a certain high-speed railway in the Northeast China as an example, focusing on the different opinions on how the passing signal on the EMU running track should be set and displayed, by means of deep analysis of relevant stipulations in technical standards, and in combination with actual application cases, eventually puts forward a reasonable mode for setting up and displaying the passing signals with which the passing ability of the EMU running track could be better. Also, the paper suggests how to further expand the passing ability of EMU running track.
