摘要
针对近来就地震危险性分析中对地震烈度衰减的不确定性校正方法逻辑上缺陷的批评,在严格限定烈度是一有序分类变量、等震线是烈度分区的外包线的基础上,本文提出了一个简单实用的校正方法,并通过实例比较了不同方法得出的结果在数值上的差异。
An uncertainty correction approach for macroscopic intensity attenuation in seismic hazard analysis is presented. It is aimed at the criticism on the logical defect in the procedure currently used. The intensity is strictly regarded as an order-classified variable and the isoseismal contour is dealt as the envelop of an intensity area.Two city towns and a region in North China were selected as the case studies to show the advantage of the suggested approach.
