Abstract

The Hoek-Brown model for near-homogeneous rock masses will, in some cases, overpredict the tensile strength of the material. In some cases this can lead to unsafe design of structures. Therefore, a tension cut-off is introduced and the model is implemented into an elasto-plastic framework for use with the finite element method. The use of the model is illustrated with a computational example calculating the safety of mining tunnel roof.
