套轨铁路信号设计中若干关键技术问题的探讨

Discussion on Some Key Technical Problems in Signal Design of Gauntleted-gauge Railway

为推进我国标准轨铁路与“一带一路”沿线国家铁路的接轨,研究套轨铁路成套技术势在必行。目前,国内尚无完整配套套轨铁路的信号定型设备和相关标准设计资料。本文针对套轨铁路的不同形式(三轨、四轨),对套轨铁路道岔纳入联锁控制、列车轮对的轨道占用检查技术、车地信息传输等问题开展专项研究,探究成果可为相关工程提供借鉴。

In order to promote the integration of China s standard gauge railway with the railways of countries along the"Belt and Road Initiative",it is imperative to study the complete set of technology of the gauntleted-gauge railway.At present,there is no complete signal prototype equipment and relevant standard design data for gauntleted-gauge railways in China.In the paper,according to the different forms(three-track,four-track)of gauntleted-gauge railways,the issues such as interlocking control of turnouts in gauntleted-gauge railways,track occupancy inspection technology of train wheelsets,and train-ground information transmission,etc.are specially researched.The research results can provide references for related projects.
