摘　　要：针对多线共咽喉大站信号平面图设计中遇到的进路信号机、进路表示器以及地面载频设置的有关问题,结合相关规定及需求分别进行探讨。提出将具有出站性质的正线信号机直接设计为出站机构,以满足纵列式车站正线信号机的设置需求;对于超过7个发车口的车站设置进路表示器时,通过3种方案比选,提出有条件按方向别代替线路别的方法;对比分析了上下行交叉车站站内正线载频切换和不切换2种设置方案,采用按统一设置地面载频的设计方案。In view of the problems related to the setting of route signal,route indicator and ground carrier frequency in signal layout design of the shared-throat multi-mainline station,this paper discusses them respectively in combination with relevant regulations and requirements.It is proposed to directly design the main line signal of outbound property as the starting signal to comply with the setting demand of signals on mainline in the longitudinal-type station.From the comparison of three schemes,a method that conditionally setting route indicator in the station with more than seven departure directions according to the direction-type instead of line-type is put forward.Comparative analysis of the mainline carrier frequency switch/un-switch setting in the up-anddown crossing station,the scheme of setting ground carrier frequency uniformally is proposed.
