| Description | The REV (Representative Elementary Volume) in fractured rocks can be defined as a critical volume beyond which all equivalent constitutive properties remain constant with the increase of the sampling volume. In this paper, a two-dimensional DEM code (UDEC) was used for the calculations of mechanical REV and equivalent mechanical properties (Young's modulus and Poisson's ratio) for two rock formations and one fault zone at Sellafield, UK. The results show that the mechanical REV is around 10 m × 10 m for all the formations considered and the REV and equivalent properties are subject to the block size and fracture properties. The results demonstrate that the DEM modeling can be an effective tool for the homogenization of mechanical properties of rock masses.
