摘　　要：基于宁洱6.4级地震的实际地震台网观测数据,结合云南分区地震动特性,以回归分析的方法对此次地震中地震动大小进行衰减分析,以此衰减到场地基岩的理论地震动值,通过一维场地土层地震反应技术分析,得出场地结构物的地震动大小输入,以期为震害分析做出数据支撑。Based on the practical observation data of network of the 6.4 grade earthquake in Ning＇er, combining with the vibration features in Yunnan partition, it gets attenuation analysis on magnitude in this earthquake based on the method of regression analysis. According to the theory earthquake motion value of attenuation and field soil, through the earthquake reaction technology analysis of one-dimensional field soil, gets the motion size input of the earthquake of the field structure, so as to provide data supporting for earthquake damage analysis.
