| Abstract: | The influence of discontinuities is studied by numerical stimulation of squeezing behavior of New Guanyin Tunnel in Taiwan. Analysis results indicate that discontinuities dominate the characteristics of deformation and failure patterns of surrounding rock masses of the tunnel. The large long-term deformation during tunneling is studied by considering the strain-softening post-peak behavior and time-dependent mechanical properties of intact rock and joints. |
