摘要:用Campbell和Bozorgnia建立了cB—NGA地震动衰减关系模型,计算出PGA预测值,分析了在不同矩震级、不同断层距及PGA值的情况下,预测值和观测值随机误差的均值肛及随机误差的标准差a,找出了PGA衰减关系误差分布特点。
CB-NGA ground motion attenuation relationship built with Campbell and Bozorgnia was used to count PGA predicted value, which analyzed the mean value/x and random error or of predicted values and observed values in different moment magnitudes and fault distance. The error distribution characteristics of PGA attenuation relationship were found.
