武广客运专线双块式无砟轨道静态调整技术

武广客运专线在国内首次采用CRTSⅠ型双块式无砟轨道道床,铺设跨区间无缝线路。在无缝线路铺设完成,以及长钢轨应力放散、锁定完成后即可开展轨道精调工作。轨道精调分为静态调整和动态调整两个阶段。结合工程实践从施工准备、数据采集分析及现场调整等对无砟轨道静态调整技术进行阐述。

Static Adjustment Technology for Double Block Type Non-ballast Track of Wuhan-Guangzhou Passenger Dedicated Line

Wuguang Passenger Dedicated Line adopted for the first time in our country the CRTS I Type double-block non-ballast roadbed and laid continuous welded rail crossingzones.After the laying of the continuous welded rail,distributing and locking in of the long steel tracks strain,accurate adjustment is done.There are two stages of accurate adjustment: statistic adjustment and dynamic adjustment.Combined with works experience,the paper described static adjustment technology of non-ballast track from its construc...
