Abstract: Discrete element method (DEM) based numerical simulation is conducted for the jointed rock under uniaxial press loading. The simulation results have a good agreement with the theoretical results obtained by analyzing the space parameters of joints, which proved the correctness of DEM numerical simulation. The results of DEM agree well with the one of FEM when joints are crosscut each other. The computation results showed quantitatively the anisotropy and size effect of jointed rock.

Key words: elastic modulus, 3D-DEM, joint parameters
