Tunnel Excavations in 3D FEM - MIDASoft

The stress state induced by construction of a shallow tunnel (secondary stress state) is three-dimensional (3D) in general. The correct simulation of the 3D load transfer, occurring ahead of and behind the tunnel face and resulting in transverse and longitudinal arching around the unsupported section at the tunnel face, is of particular importance.

A 3D finite element simulation model for TBM tunnelling in

A three-dimensional finite element simulation model for shield-driven tunnel excavation is presented. The model takes into account all relevant components of the construction process (the soil and the ground water, the tunnel boring machine with frictional contact to the soil, the hydraulic jacks, the tunnel lining and the tail void grouting). The paper gives a detailed …
