利用不同导线测量方法对地铁隧道贯通误差的估算

Estimation of the Through Error of Subway Tunnel by Using Different Traverse Measurement Methods

为了提高地铁隧道地下控制测量的精度,论文采用双导线法进行地铁隧道测量贯通误差分析,并结合某市的地铁交通工程,分析研究了测量结果.

In order to improve the accuracy of underground control measurement of subway tunnel,this paper adopts the double-wire method to analyze the hole-through error of subway tunnel measurement,and takes the subway traffic engineering of a city as an example to analyze and study the measurement results.
