Stability analysis of a fire‐loaded shallow tunnel by means of a thermo‐hydro‐chemo‐mechanical model and discontinuity layout optimization
When subjected to fire loading, shallow tunnels may experience loss of stability. This may
result in large deformations and ultimately in local collapse of such structures. High …
