深圳地铁4号线信号系统贯通改造技术研究

Study on Through Reforming Technology of Signaling System in Shenzhen Metro Line 4

城市轨道交通线路分段开通然后实现全线贯通衔接是目前城轨建设的普遍做法。本文以深圳地铁4号线北延段为例,重点阐述了北延段与既有线信号系统贯通改造的技术方案,总结了贯通改造过程中需要重点关注的问题。

Multi phase operation mode of an urban rail transit line and realization of through connection of the whole line in the last phase is quite common in the construction of urban rail transit. Taking the north extension section of Shenzhen Metro Line 4 as an example, the discussion is focused on the technical solution for through reform of the signal system of the northern extension section as well as the signal system of existing line. In the end, major concerns in the process of through reform are summarized.
