高速铁路CRTSⅡ型轨道板精调技术

摘要

Introduced in the paper are the precisely adjusting processes for type-II CRTS track slabs of the Beijing-Shanghai High-speed Railway, namely, installing an electronic total station at the reference point of the track, fixing the directional prisms, provd%介绍京沪高速铁路CRTSⅡ型轨道板精调工艺流程,即在轨道基准点（GRP）上架设全站仪、固定定向棱镜,在承轨槽处放置测量标架,通过测量确定标架上每个棱镜存在的位差,进行轨道板调整。探讨轨道板精调施工技术,为今后提高CRTSⅡ型轨道板精调工艺和质量提供参考。
