摘　　要：对遂渝铁路无碴轨道综合试验段中出现的低净空隧道的接触悬挂方式进行探讨,采用方案优化比较选择的方法,对于类似的低净空隧道的处理提出了一些可靠,可行的方案,解决了遂渝线无碴轨道试验段的低净空隧道问题,取得了良好的效果。In order to resolve the low headroom tunnel construction problem in the electrical high-speed ballastless track, by introducing and discussing the contact suspension in low headroom tunnel of the experimental section of SunYu ballastless track, this paper used the method of selection optimization comparison and selection, and put forward some reliable and feasible schemes for similar constructions. As a result, some contact suspension problems of low headroom tunnel were resolved with a satisfactory effect.
