| 摘 要： | 本文根据地震动衰减的理论分析结果和强震观测记录，提出了一种新的拟合地震动衰减关系的两步法，并用新近补充，完善的美国西部强震记录，对PGA，EPA和EPV衰减特性进行了分析，结果表明，建议的方法能反映近场强震地震动饱和效应和大震远场衰减的特点。

| Abstract: | A new two-steps method for fitting ground motion attenuation relationship is presented in this paper, based on theoretical analysis results of ground motion attenuation and ground motion recordings. Attenuating characteristics of PGA, EPA and EPV are studied by using newly supplemented data in the western part of USA. The results indicate that the presented method could illuminate the saturation effect in near field and attenuating characteristics of strong ground motion in far field from large earthquake. |
