✦ Synopsis

Based on the six possible and dierent failure mechanisms de®ned in part I, a criterion to identify which is the particular failure mechanism is developed. The rock mass is assumed to have transverse isotropic strength. The particular mechanism depends on the geometrical situation, the geomechanical parameters and the boundary conditions. A series of graphs are provided allowing this identi®cation. Some examples of parametric studies are described and the ultimate bearing capacity is solved for a wide range of situations of transverse isotropy. A series of nomograms, to ®nd the bearing capacity of a strip foundation, are provided for the entire range of possible dips representing the planes of weakness, when the foundation surface is horizontal.
