摘要
针对高速公路不同测量基准下平面控制测量误差问题,分别提出了分段平差方法和整体平差方法来消除不同等级控制点之间和不同测量系统之间的坐标误差,实践证明在路线中线偏差处理方面具有重要的实用价值。
Aiming at true error of plane control survey under different survey datum during highway construction, this paper respectively gave the segmented survey adjustment and combined adjustment to eliminate the coordinate errors in control points of different grades and different surveying systems. Practice has shown that the methods have important applications in center-line deviation processing of roads.
