Abstract: Based on the establishment of the intensity attenuation relation of Jiangxi Province and its adjacent areas by analyzing isoseismic line data,we develop the attenuation relations for horizontal peak ground acceleration and response spectrum of the areas by selecting the west of USA as the reference region and using the transforming method.In comparison with the seismic motion attenuation relation of eastern China,the result better represents the features of historic and modern earthquake damage distribution in the area,and may contribute to seismic safety evaluation,earthquake damage prediction and fast loss assessment.

Key words: ground acceleration, seismic intensity, attenuation relation, Jiangxi Province and its adjacent areas

摘要: 在利用江西省及邻区的地震烈度等震线资料建立该区地震烈度衰减关系的基础上,以美国西部为参考地区,转换得到了相应的水平向基岩峰值加速度与反应谱衰减关系,并与中国东部地区的地震动参数衰减关系进行了对比,其结果更加符合该区历史和近代地震震害分布的地域性特点,可进一步应用于地震安全性评价、震害预测、损失快速评估等研究。
