摘要
双块式无碴轨道是一种适用于客运专线的新型轨道结构,它具有高平顺性、高稳定性、刚度均匀性好、结构耐久性强和少维修的特点。介绍路基上双块式无碴轨道结构特点、施工方法、施工工艺流程以及质量控制和施工注意事项。
Double-block ballastless track applied on PDL is a new track structure. It is a low maintenance durable track structure with high stability, high geometric regularity and uniform track stiffness. This paper introduces the constructive components of double-block ballastless track on subgrade, the construction method and process and quality control etc.. It is an important guidance to plan and manage such construction.
