解决无碴轨道电路问题的技术途径

Technical Approaches to Resolve Ballastless Track-circuit Problem

在无碴轨道线路上,无绝缘轨道电路传输长度的缩短不单是增加电务设备和运营阶段养护维修费用的问题,在快速和高速条件下,也是安全问题。讨论了解决该问题的三个技术途径,指出采用涂层钢筋是切实可行的措施。介绍了源于防腐工程的涂层钢筋技术发展与应用情况,提出在无碴轨道结构中应用时需研究解决的关键技术问题。

On ballastless track, shortening the transmission length of non-insulation track circuit is not only the question ofincreasing permanent way equipment and maintenance cost in operation period, but also the question of safety under the fast-speed and high-speed condition. The essay discusses three technical approaches to resolve those questions, points out thatadopting coated reinforcing steel bar is a feasible measure, introduces the technology development and application status ofcoated reinforcing steel bar which roots on anticorrosion engineering, and puts forward the key technical issues that need to beresearched and resolved during applying the ballastless track structure.
