| Abstract: | 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. |
| Keywords: | Tunnel Soft surrounding rock Large deformation High ground stress Deformation control |
