无砟轨道预精调技术应用研究

Application Research on Pre-Fine Adjustment Technology of Ballastless Track

结合郑万铁路项目CRTSⅠ型双块式无砟轨道长轨精调实际案例,通过轨道预精调技术与常规精调技术扣件使用率的对比,研究无砟轨道预精调技术对于轨道精调成本的正面效益,为后续高铁施工中轨道精调技术升级研究提供思路和实验数据。

Combined with the actual case of CRTS Ⅰ double block ballastless track long track fine adjustment of Zheng Wan railway project, this paper studies the positive benefits of ballastless track fine adjustment technology for track fine adjustment cost through the comparison of fastener utilization rate between track fine adjustment technology and conventional fine adjustment technology, so as to provide ideas and experimental data for the upgrading research of track fine adjustment technology in the subsequent high-speed railway construction.
