The aim of this study is to assess the three-dimensional (3D) stability of the tunnel face with considering the possibility of the upper partial failure in layered rock masses. The failure characteristic of the rock material is denoted by the nonlinear Hoek–Brown failure criterion, and a multi-tange...
