摘要
介绍了福厦铁路黄晶岭隧道GPS平面控制网的建立、施工情况,讨论了该隧道数据处理等方面的相关问题,以期对同类工程能有一定的借鉴作用.隧道控制测量结果表明:尽管采用单频GPS接收机和广播星历等一般测量条件,但由于观测及数据处理方案科学合理,短边边长精度仍能达到5 mm以内,且其它各项精度指标均能满足规范和工程要求.
Establishment of GPS horizontal control network and the construction of Huangjingling Tunnel are introduced and data processing is analyzed, to exemplify other similar projects to a great extent. The result of tunnel control surveying indicates that short-side length is so precise as to be less than 5 mm, and all other indices of precision meet with the specifications of surveying and the project due to the scientific scheming of observation and data processing, despite the use of such general observational conditions as single-frequency GPS receiver and broadcast ephemeris.
