隧道贯通误差的估算方法及地表导线测量的设计方法

Methods of Calculating Tunnel Transfixion Errors and Surface Traversing Design

在贯通误差的处理中，考虑到起点、终点间的各边方位角以及边长、角度平差的综合影响．提出了一种地表导线测量所引起的贯通误差估算方法及设计方法．

With consideration of the synthetical effects of each azimuth between the starting point and terminal point, of the side length and angle adjustment, in dealing with transfixion errors, the author shows us some methods of calculating tunnel transfixion errors and surface traversing design.
