Stability evaluation of tunnels in steeply dipping layered rock mass using numerical models: a case study

Stability evaluation of tunnels in steeply dipping layered rock mass using numerical models: a case study

Abstract Tunnel stability is a critical factor in complex geological conditions, particularly in rock masses with steeply dipping layers. Among widely used methods, the Convergence–Confinement Method (CCM), a prevalent two-dimensional (2D) approach, effectively captures the relaxation process preced...
