在隧道施工过程中,为了确保隧道顺利贯通,应对隧道洞内控制网的布设及所需测量精度进行预先计算,从而确定隧道贯通所需要的洞内控制网的导线等级。
In the process of tunnel construction, in order to ensure smooth tunnel, the layout of the control network in the tunnel tunnel and the required measurement accuracy should be pre-calculated to determine the conductor level of the tunnel control network required for tunnel penetration.
