摘　　要：在实现城际铁路和城市轨道交通的互联互通中,CTCS-2级信号系统有着较为广阔的应用场景;但随着地下线路的日益增多,其在到发线有效长度等方面,对土建工程投资有着重大影响。通过分析到发线有效长度的组成,重点研究安全防护距离、站台端部至应答器组之间的预留距离,结合系统选型和技术发展路线,有针对性地提出优化方案,从而有效降低工程造价。CTCS-2 signaling system has wide application scenarios in the interoperability of intercity railway and urban rail transit,however,with the increasing number of underground lines,it has a great impact on the investment of civil engineering in terms of effective length of arrival&departure track.By analyzing the composition of the effective length of arrival departure track,this paper mainly studies the safety protection distance and the reserved distance between the platform end and the balise group.Taking into consideration of the system selection and technical development roadmap,it suggests the optimization scheme,effectively reducing the project cost.
