GPS定位系统在隧道施工控制测量中的应用

Application of GPS Orientation System in the Survey Construction of Tunnels

文中以广梧高速公路石牙山隧道利用全球定位系统(GPS)进行施工控制测量为实例,简述了全球定位系统(GPS)的基本组成和测量原理,并分别通过利用全站仪进行传统导线测量和GPS定位系统测量两种方法的对比,总结了GPS应用于隧道工程控制测量所具有的卓越性能。

Taking the construction controlling survey by GPS orientation system in Shiyashan Tunnel of Guangwu Freeway as an example, this paper introduces the basic composing and principle of survey. Furthermore, by contrasting traditional traverse method to GPS orientation system, the paper summarizes the excellent performance of GPS in the survey construction of tunnels.
