Dynamic Effect of Soil-Tunnel Interface Under Dynamic Loading

Resumo

The resilience of the Daikai subway station during the Kobe earthquake is taken as a case study of tunnel endurance at various points under different soil conditions. The Mohr-Coulomb material model is used. The effect of peak ground acceleration, overburden depth, and soil-tunnel interaction is analyzed. The effect of cohesive force on stresses for various soil tunnel interface conditions (full slip, partial slip, and no slip) is studied. The model is validated by comparing axial force and displacement, and its results are consistent with those presented in the literature.
