DOI: 10.1007/s12205-019-1048-4
Abstract: This paper aims to assess the face stability for tunnels excavated in weathered and saturated rock masses using the Hoek-Brown failure criterion. With resort to the upper bound theorem of limit analysis, a 3D rotational… read more here.

DOI: 10.3846/jcem.2021.15020
Abstract: Breakout is a shear failure due to compression that forms around the borehole due to stress concentration. In this paper, the breakout theory model is investigated by combining the equilibrium elasticity equations of stress around… read more here.
