本文通过选取没增设GRP点的哈大客运专线和增设GRP点的沪宁城际铁路，总结对比其实际无砟轨道测量经验，研究GRP点在CRTS玉型板施工中的作用和意义，说明GRP点在无砟轨道测量系统中的不可替代性，为后续高铁铁路、客运专线施工建立更加完善和科学的测量控制网提供依据和参考。%This article selects Harbin-Dalian passenger dedicated line without GRP point and Shanghai-Nanjing intercity railway with GRP point, compares the experiences in the actual ballastless track measurement and researches the role and significance of GRP points in CRTS Ⅰ plate construction. The result shows that GRP point is irreplaceable in ballastless track measurement system, which provides reference for subsequent high-speed railway and passenger dedicated line construction to build a more perfect and scientific survey control network.
