摘　　要：本文根据洪华生(Der Kiureghian-Ang)断层破裂模型,对不同尺度的潜在震源区及各种震源参数进行了地震危险性数值计算。分析了潜在震源区划分范围,震级上限M_u及β值等地震活动性参数的不确定性对地震危险性分析的影响,其结果可供地震区划及工程地震等工作者参考。Based on fault rupture model of A. Der Kiureghian and A. H-S. Ang,seismic risk has been numerated for various earthquake source parameters and potential earthquake source regions of different size. Influences of uncertainties in seismicity parameters,such as confines of potential earthquake source region, upper limit of magnitude, Mu and β value, on calculated seismic risk have been analyzed. The results of this study are of value for seismic regionalization and engineering seismology.
