... strength criterion is proposed for anisotropic rocks and jointed rock mass. The proposed criterion is an extension of Jaeger two-dimensional (2D) anisotropic criterion into three-dimension (3D) using Mogi-Coulomb strength criterion. It is concluded from the study that the most critical anisotropic plane is...
