Modelling of Tunnels construction by Dr Tony Swain

This analysis involves the construction of two tunnels and a station concourse. The soil model used is elastic-rigidly plastic Mohr Coulomb. The construction sequence accounts for consolidation. The analysis shows that tunnel movement and surface deformation are dependent on consolidation effect, tunnel size and proximity to the ground surface.
