摘要:

论述了利用双交叉导线测设长大隧道洞内控制网的方法。该方法能增强洞内导线网形的结构稳定性,提高隧道贯通的精度。

关键词: 交叉导线, 洞内控制网的建立, 精度分析

Abstract:

This paper discusses the methods of utilizing the double-intersecting conducting wires in long and large cross section tunnels to test the tunnel's internal control network. This method is developed to strengthen the structural stability of the net-shaped conductingwires inside the tunnel,and to improve the boring precision across the tunnel.

Key words: intersecting conducting wires, establishment of a tunnel's internal control network, precision analysis
