摘要
本文介绍了在长大隧洞施工中,在极其破碎的断层带这种不良地质段,出现TBM机头被困等问题。通过采用上导洞开挖、氰凝材料注浆等施工方案,确保了工程正常顺利施工。
The paper describes the problem that TBM＇ s handpiece gets trapped in the unfavorable geological section which is extremely fragmentized fault zone during the construction of the tunnel. By adopting construction schemes such as top heading excavation, cyanide cementitious materials grouting, and so on, the engineering is ensured to be carried out smoothly.
