摘要
According to the continuity of the natural rock, a method for mesostructure of heterogeneous rock material based on spatial correlation character was proposed.The present method was incorporated into particle flow code (PFC) and a numerical model was established to accurately and efficiently reflect the heterogeneity of rock.Taking Guangdong Conghua granite for example, the numerical models of PFC2d and PFC3d for actual mesostructure of granite were presented.The simulation shows that the method describes the actual heterogeneity for rock, meanwhile, avoids the complexity and low efficiency for the exiting digital image processing methods.The method provides an innovative way for the investigation on mechanical behavior of the heterogeneous rock-like materials.
