Due to the presence of joints, jointed rock masses show anisotropic and scale (size) dependent mechanical properties. A brief description of a recently suggested technique which has the capability of estimating the anisotropic, scale-dependent deformability properties of jointed rock is given. Based on this technique, the following have been obtained: 1) 3-D plots to show the variation of deformability parameters of jointed rock with joint geometry parameters, 2) a relation between the deformability properties of jointed rock and fracture tensor parameters, 3) an incrementally linear elastic, orthotropic constitutive model to represent the pre-failure mechanical behaviour of jointed rock, and 4) some insight to estimate the representative elementary volumes (REVs) and REV property values with respect to the deformability properties of jointed rock. -from Author
