长大隧道控制测量方法综述

Summary of Control Survey Methods in Long Tunnel Construction

根据长大隧道施工控制测量的建网理论,阐述如何实现测量精度及误差控制的方法。详细地讨论了采用精密导线法及GPS方法组建隧道控制网并进行测量控制的方法,阐述贯通精度预计计算及控制网平差处理一般规则,对长大隧道的控制测量具有较重要参考价值。

On basis of the network establishing theory of control survey in long tunnels, this paper presents the method of improving the survey precision and controlling the errors. Control network establishing and survey control by means of precise traversing method and GPS method are discussed in detailed. Furthermore, the general rules for estimating the hole-through error and control network adjustment are given. This paper can provide reference for survey control of long tunnels.
