摘要

采用考虑地震加速度的近场距离饱和与震级饱和特征模型的衰减关系,通过收集关中平原区及邻区大量的地震资料,建立起本区的地震烈度衰减关系。将美国西部地区作为参考区,采用不同映射的转换方法,得到了关中平原区的基岩水平加速度衰减关系,并对不同的映射方法得到的结果进行了对比分析。
Using the attenuation relationships which consider the near-field distance and magnitude situation of seismic acceleration and the characteristic models,and by collecting a large number of seismic data of Guanzhong and its adjacent area,the attenuation relations of bedrock horizontal ground acceleration are established.Attenuation relationships of seismic ground motions in western United States are taken as reference for this study.And new attenuation relationships are obtained from different mapping transformation methods for the Guanzhong plain region.Results from different mapping transformation methods are compared and analyzed at last.
