摘　　要：在广深港高铁项目中,为满足隧道通风井区域仅有一辆列车运行,且列车运行间隔3 min的需求,在西九龙站(WKT)下行咽喉正向发车口特别设置一架总出站信号机SZ。由于该站咽喉区比较短,设置该信号机后,对该发车口的接、发车进路以及调车进路的联锁关系都产生影响。针对这些影响进行深入分析,通过卡控分段进路性质,增加特殊联锁关系检查,调整调车信号关闭时机和区段解锁方式等方法,解决进路分割,无岔调车进路等问题。采用该方案既满足运营要求,又保证安全和效率。In the Guangzhou-Shenzhen-Hong Kong Express Rail Link project,an advance starting signal SZ is specially installed at the forward departure exit in down direction throat area of West Kowloon Station(WKT)in order to meet the demands of only one train running in the ventilation area and a 3-minutes interval between trains.Since the throat area of this station is relatively short,the setting of the signal has impacts on the interlocking logic of the arriving and departure route as well as the shunting route of this departure exit.In this paper,an in-depth analysis of these effects is carried out,and the problems of route segmentation and switchless shunting route are solved by controlling the nature of segmented route,adding special interlocking relation checks,adjusting the timing of shunting signal at stop and section unlocking mode,etc.The use of the scheme not only meets the operational requirements,but also ensures safety and efficiency.
