| Abstract: | Tunnel total collapse generally occurs in the soft rock of tunnel section. Principle of Strength Reduction is used to make numerical simulation analysis to simulate the occurrence and development of the runnel total collapse, and it can also used for the pre-coUapse numerical simulation analysis of the tunnel. |
