摘要
为了提高隧道控制网的测量精度,保证隧道施工正确贯通,采用GPS对秦岭隧道群进行控制测量,满足了自然环境恶劣、交通不便、使常规方法进行隧道控制测量难以达到精度要求的目的。
In this paper, GPS is applied to the control survey of Qinling tunnels. It is proved that this control survey method is not influenced by the entironment and transportation, and improves the measurement accuracy which the traditional tunnel control survey method could not reach.
