By studying on scale dependency of mechanical properties of the rock mass, REV size was determined. On the other hand, for continuum modeling of rock mass because of the inherent uncertainty in geometrical and mechanical characteristics, 39 sample models were generated stochastically based on geometry variation of joints. Uniaxial and triaxial compressive tests were performed and finally, distributions of UCS, deformability modulus, cohesion, and friction angle of rock mass were obtained. These can be used for reliability and probability investigation of the rock mass.
