呼和浩特机场路立交桥施工测量方法精度比较

Comparison of accuracy in survey methods used for construction of Hohhot Airport Interchange

呼和浩特机场立交桥的施工中,分别使用了坐标导线测量和小三角测量。经比较,两种测量方法的精度均满足规范要求,全站仪坐标导线测量大大减小内业计算和测量人员的工作量,提高了测量速度。

The coordinate traverse survey and trigonometric survey were carried out respectively during the construction of Hohhot Airport Interchange. Having compared with both methods, the accuracy of two survey results can meet the requirements of the specifications, and the office calculation and working capacity of survey crew can be greatly reduced with the above traverse survey by using the total station, and pick up speed of surveying.
