  Face instability and surface settlements in shallow tunnels under seepage flow

  Abstract: In the present paper, the effect of face instability on the surface settlements of a shallow tunnel driven in cohesive- frictional soils, under seepage flow conditions was studied numerically. A three-dimensional finite element model was created, and several coupled analyses were performed employing elastic-perfectly plastic soil material. A parametric study was also done to investigate the...
