针对隧道测量中的难点问题,提出了运用GPS测量手段和精密导线测量的方法来解决特长隧道定向问题;依托全球卫星定位系统建立高等级控制网,得到准确的控制点坐标;研发的基于测量机器人的多测回测角软件用于隧道内导线测量,减轻隧道内作业强度,提高了测量精度。 In order to solve the difficult problem in tunnel measurement, the method of GPS measurement and precision wire measurement is proposed to solve the problem of long tunnel orientation. The high-grade control network is established based on global satellite positioning system to obtain accurate control point coordinates. The multiple measurement and return angle measurement software is used to measure the inner conductor of the tunnel, reduce the intensity of work in the tunnel and improve the measurement accuracy.
