Abstract：The beam-particle model (BPM2) is used to model fracturing behavior of rocks. This numerical method used simulating damage and fragmentation phenomena of rock-like materials is presented on the basis of discrete element method (DEM) and lattice model. Random distribution of three types of beams in BPM2 is employed to simulate the spatial variation of mechanical parameters of brittle rock-like materials. The model of anisotropic media is generated automatically and used to investigate the mechanical behaviors of these low-porosity materials. The numerical simulation results of fracturing process in anisotropic brittle rock-like materials under uniaxial compression show that the initiation，propagation and linking of the fractures in the rock samples at mesoscale level produce the macro-failure of rock samples. The comparison with failure modes of pillars in underground mines proves this method is appropriate and efficient for simulating fracture propagation of anisotropic rock-like materials.
