Strength characterisation of shale using Mohr-Coulomb and Hoek-Brown criteria

Strength parameters of rock material are usually determined from laboratory test on intact rock samples. Uncertainties arise in predicting the behaviour of a rock mass under confinement due to the presence of discontinuous. Compared with the intact rock, discontinuity such as joint induces inhomogen...
