变形控制是炭质板岩隧道施工中的重点与难点。本文以木寨岭隧道工程为例,深入探讨产生大变形的原因以及常用的勘察手段,有针对性地提出施工技术要点,以提高隧道施工效率,确保工程质量。
Deformation control is the key and difficult point in the construction of carbonaceous slate tunnel. Taking Muzhaoling Tunnel Project as an example, this paper discusses in depth the causes of large deformation and the commonly used survey methods, puts forward the key points of construction technology in order to improve the tunnel construction efficiency and ensure the project quality.
