Face stability of shallow tunnels

Tunnels with low cover are very often headed using the shield technique in order to prevent excessive ground movements during tunnel advance and to secure a safe working environment for the support works. Therefore the correct application of a face support pressure is of great importance.

In this project the stability of the tunnel face is investigated by means of laboratory experiments and three-dimensional finite element computations.
