Practically, r(xk masses are in compression and shear state because of the in situ stresses. The unloading of the rock nnasses near excavated slopes causes tension-shear stress state in part of the slopes. Consequently, it is necessary to set up constitutive model of jointed rock masses considering both compression-shear and tension-shear mechanisms. 

According to the principle of self-consistency (Kemeny, 1986), the compliance tensor of a jointed rock mass under tension and shear stress state can be deduced as... 

When rocks and minerals are stressed above their tensile strength they break. Commonly, rocks fracture along joints, fissures, or planes that have developed during cooling, tectonism, sedimentary processes, or along lines of weakness at the mineral grain boundaries. When buried rock masses are... 

Classification of the rock mass around caverns was made according to the Rock Mass Rating (RMR) System (Bieniawski, 1989) and the Tunnelling Quality Index (Barton et al, 1974). Parameters were selected by the geological site investigation, the characteristic data for the intact rock, the joint sets and the in-situ stresses.
