摘要
引黄输水工程,属长距离隧洞工程,为保证隧洞顺利贯通,有必要对施工过程进行及时、准确的检测,主要是对隧洞轴线的检测。本项目中,利用徕卡TS30高精度全站仪检测隧洞外施工控制点和隧洞内关键控制点坐标,并对三角高程测量和导线测量的误差进行了推导和分析。
The Yellow River Diversion Project is a long-distance tunnel project.In order to ensure the smooth connection of the tunnel,it is necessary to detect the construction process timely and accurately,mainly the detection of the tunnel axis.In this project,Leica TS30 high precision total station is used to detect the coordinates of construction control points outside the tunnel and key control points inside the tunnel,and the errors of trigonometric leveling and traverse survey are deduced and analyzed.
