摘　　要：为研究地震动参数之间的相关性,以及地震动参数与结构整体破坏指数之间的相关性,分别研究了远场地震动参数之间的相关性和近场地震动参数之间的相关性;比较了远场和近场地震动参数相关性之间的差异及远场和近场地震动参数与结构整体破坏指数之间的相关性.结果表明,某些地震动参数间存在着很强的相关性,近场地震动参数之间的相关性普遍弱于远场.给出了可用来估计结构破坏程度的地震动参数.This paper presents the results of research on the correlation among seismic ground motion parameters and their relationship with the overall structural damage index （ OSDI ）. Three aspects has been carried out in this research ： The first aspect of the research is to study the correlation among far - field and near-field seismic ground motion parameters, respectively; The second aspect is to compare the differences between correlation among far-field seismic ground motion parameters and near-field ones; And the third aspect is to analyze the correlation between seismic ground motion parameters and overall structural damage index （ OSDI ）. It is concluded that there exists strong correlation among some seismic ground motion parameters for both farfield and near-field ground motions, and the correlation among far-field seismic ground motion parameters is stronger than that among near-field ones. The seismic ground motion parameters that can be used to estimate the damage degree of structures are also recommended.
