摘　　要：文中利用我国大陆地区的8次破坏性地震中获取的115条强震记录及其对应的震后调查烈度资料数据,通过普通最小二乘法和加权最小二乘法建立了24种地震动参数与地震烈度的回归公式,对地震动参数与烈度间的相关性进行了对比分析。结果表明:与烈度相关性最好的参数分别是5%阻尼比的水平向速度反应谱均值PSVs及峰值速度PGV。此外对本文结果与国内外类似的一些统计关系做了对比分析,以期对我国仪器烈度标准的建立提供参考。In this paper, we analyze the correlations of seismic intensity with 24 ground motion parameters calculated from 115 strong ground motion records obtained in eight destructive earthquakes of China by using the least squares method and weighted least squares method. The correlation between ground motion parameters with seismic intensity is also studied. The statistics results indicate that 5% damping ratio of the mean horizontal velocity response spectra PSVs and peak velocity PGV are the best two parameters correlaed with the seismic intensity. In addition, comparative analysis has been done between the results of this paper with similar results, to provide a reference for the establishmental of the standard instrumental intensity in our country.
