【摘要】 本文采用地震震级的模糊信息提出确定地震重现关系的一种方法。在分析中应用顶角法把传统的最小二乘法加以延伸来处理模糊地震震级。通过若干事例讨论与验证了地震重现关系中采用地震震级的清晰值与模糊值的差异。本文提出的模糊重现关系可用于地震危险性分析或地震区划。更多还原

【Abstract】 This paper presents a methodology for determining earthquake recurrence relationships using fuzzy information of earthquake magnitude.And the conventional least-square method is extended to deal with fuzzy earthquake magnitude by the vertex method in the analysis. The differences between using crisp values and Vague information of earthquake magnitude in earthquake recurrence relationships are discussed and examined through several examples, The fuzzy recurrence relationship developed in this paper is intended for use in seismic hazard analysis or seismic zonation.更多还原
