【摘要】 收集江西及邻区的地震烈度等震线资料,采用椭圆长、短轴联合衰减模型和近、远场补点与长轴可转向方法,建立了该地区的地震烈度衰减关系并进行了验证,结果表明,该衰减关系符合该地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。更多还原

【Abstract】 Based on the seismic intensity data of Jiangxi Province and its adjacent area,according to the ellipse model of united major-minor axis and the method of adding control points of the near-far field,we establish an intensity attenuation relation and tested its reasonability.The result shows that this relation well represents the features of historical and modern earthquake damage distribution in the areas,and can be applied to seismic safety evaluation,earthquake damage prediction and fast loss assessment.更多还原
