GPS RTK在线路测量工程中的应用分析

Analysis of Application of GPS RTK Technique in Route Surveying

通过野外实验和生产实践,讨论了GPS RTK测量技术及在线路工程测量中的应用,分析说明10 km以下测程范围内,RTK的测量精度能满足大比例尺线路数字测图要求,并用实例验证了RTK施工放样的精度和可靠性,表明RTK测量可以较好地满足公路设计和施工中的定线、放样测量的要求。

The GPS RTK technique and its application in the route surveying are discussed by the experiments and practical applications, and in the range of less than 10 km, the RTK technique＇s measurement accuracy can meet the request of digital route mapping of the large scale. At the same time, the reliability and precision of the RTK technique＇s setting-out of construction are validated, and the results show that RTK technique can satisfy the needs of the alignment and setting-out survey which exists in the highway design and construction.
