| Abstract: | Through keeping tracking of the tunnel excavation and analysis of former geological date,it is concluded that the rock surrounding the west exit for the tunnel has sliding displacement due to weightlessness resulting from unloading.Thereafter,the preventative measures are advanced,following the assessment of the safety of the tunnel. |
