Upper-bound analysis on the face stability of a non-circular tunnel

The present paper is devoted to the estimation of the safety factor of a tunnel face with a non-circular section using the upper-bound limit analysis in combination with the strength reduction technique. Thanks to the spatial discretization technique, an advanced 3D rotational collapse mechanism is...
