摘 要：正 Several models have been used in the dynamic analysis of the fault region in order to predict features of the rupture process that gives rise to seismic excitation. The simplest and understandably more often employed laws are the slip-weakening laws and the so-called velocity or rate-weakening laws. In this paper, the region adjacent to the fault surface was modeled, including material non-homogeneities as well as the possibility of generation of new tensile cracks. By means of Monte Carlo simulation, the macro constitutive relations for the fault, which correlate the static （mean normal and shear stresses） with kinetic
