摘要
从研究秦岭隧道GPS平面控制网在复测中遇到的垂线偏差影响;高程异常值对投影面归算的影响;GPS网起算点误差对高斯平面上相对坐标值的影响出发,探讨隧道GPS平面控制网的布测方法。
This paper deals with some problems occurring in the reestablishment of Qinling Tunnel GPS horizontal control network for checking purpose,namely,the influence of vertical deflection on the accuracy of network;the influence of height anomaly error on the reduetion to network projection plane; the influence of GPS absolute positioning error on the relative coordinates of projection plane.
