摘要
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.
