3D MODELLING OF A TUNNEL RE-EXCAVATION IN SOFT GROUND

3D Modelling of a Tunnel Re-excavation in Soft Ground

The construction of the shallow tunnel at Brezno started using the Pre-Vault Method.The tunnel excavation, Booster Seats in complicated geological conditions, led to many difficulties which finally resulted in a collapse, when a significant part of the temporary tunnel lining collapsed.Various options for re-excavating the tunnel were evaluated pri
