轨道基准点(GRP)测量技术研究与应用

The Research and Application of GRP Measurement Technology

以沪宁城际铁路Ⅳ标工程为例,介绍了无砟轨道CRTSⅠ型板轨道基准点(GRP)测量方案的创新、设备工装与配套软件的研发、现场测量存在的难题与解决措施,并通过实测数据的处理分析及应用,证明沪宁城际GRP测量的成功,为今后高速铁路无砟轨道的施工提供借鉴。

Taking the Shanghai-Nanjing Intercity Railway IV section project for example, the article introduces the innovations, tooling equipment and supporting software development and the solving measures of on site measurements existing problems of CRTS I of the non stone track GRP measuring program. It proves the success Of Shanghai Nanjing Intercity GRP measurement through the practice of measuring datum processing analysis and application, providing a reference for the high speed railway＇ s non-stone track construction.
