摘要
隧道施工是个动态过程,掌子面前方的围岩经常变化。为了配合施工及确保隧道结构的安全稳定,常常会发生隧道设计变更。利用FLAC3D数值计算软件对老庄隧道设计变更进行了计算,以分析隧道结构的稳定性,对隧道设计和施工有一定的借鉴意义。
The tunnel construction is a dynamic process, and the rock in front of Tunnel face con-stantly changs. In order to meet the construction and ensure safety and stability of the tunnel structure, the tunnel design changes often occur. In this paper, tunnel design changes were calculated to analyze the structural stability of the tunnel by the numerical software of FLAC3 D, which is important to the design and construction of tunnel.
