中强地震区地震烈度和峰值加速度的衰减规律

The Seismic attenuation regularities in the moderate-strong earthquake area

通过回归分析得到了中国东部中强地震区地震烈度衰减规律 ,采用“借用法”建立了该地区峰值加速度衰减规律 .通过和华北地区地震动衰减规律对比研究 ,认为东部中强地震区地震烈度和峰值加速度衰减规律更能反映中强地震区地震破坏特点 .在中国东部 ,应用本文地震动衰减规律进行地震危险性分析计算 。

The seismic intensity and peak\|acceleration attenuation regularities are obtained by using statistical and “borrowing” methods in the moderate\|strong earthquake area in east China. After these regularities are compared with attenuation regularities in north China, these regularities are more suiable for the moderate\|strong earthquake area, and results of the seismic risk analysis are more safe by using of these regularities.
