摘要
文章结合新建兰渝线木寨岭隧道工程实践,在了解了碳质板岩地层发生大变形的原因和机理的基础上,对高地应力条件下软岩大变形的控制技术进行了分析研究,提出了处理隧道大变形应以控制为主的原则,以及确保隧道安全施工、快速通过的支护措施和变形控制对策。
Based on the construction practices of the Muzhailing tunnel on the Lanzhou-Chongqing railway and the understanding of deformation causes and mechanism of carbonaceous slate stratum,this paper analyzes techniques for controlling deformations of tunnels in soft rock with high ground stresses.It addresses control-based principles,relative support methods,and measures of deformation control used to guarantee rapid and safe construction.
