地铁既有线与延长线信号ATS子系统联接施工设计方案探讨

Study of Construction Design Scheme of the ATS Subsystem Connection between the Existing Lines and the Extension of Subway

随着地铁建设规模的扩大,线网的不断完善,既有线路的延伸也越来越多。以广州市轨道交通3号线及其北延段信号系统工程无缝贯通运营为例,对ATS数据传输系统的构成、网络组成形式及与既有线的联接等关键点的主要施工设计方案进行探讨,为今后类似工程的实施提供经验和参考。

With the expansion of subway construction scale,the continuous improvement of subway line networks,extension to the existing subway lines is increasing more and more.Taking the seamless linking up between Guangzhou Rail Transit Line 3 and signal system of its north extension section as an example,the paper explores the composition of ATS data transmission system,network formation,and the main construction scheme of key points like the joint with existing line,wishing to provide experience and reference to the implementation of similar project in the future.
