摘要
In this paper, three kinds of heterogeneous faults with 81×81 cells are set up using celluar automata models and simulated for explaining the inconsistency between the observations and fractal-based model. The results show that the G-R relations behave not in simple self-similarity but multi-fractal, and with the increasing of heterogeneity the fracture process tends to turn from brittle to plastic behaviors. The results from computer simulation are consistent with observations from detailed seismicity studies.
