摘要: 论述了利用高精度GPS作长大隧道洞外控制网的方法,增强了洞外控制网网形的结构稳定性,提高了隧道贯通的精度。

关键词: 独立控制网, 洞外控制网的建立, 精度分析, 贯通精度

Abstract: This paper discussed the method to adopt high-precision GPS as the control network for long and large tunnels. So that the stability of the network structure of the control network outside the tunnel can be enhanced and that the tunnel piercing accuracy can be improved.

Key words: independent control network, establishment of the control network outside tunnels, accuracy analysis, piercing accuracy
