摘要

本文以美国加州3次破坏性地震和2008年中国汶川Ms8.0地震中所获得的强震记录作为数据源,应用最小二乘法进行线性回归,得到了不同地震动参数与烈度间的相关性。统计发现,在地面加速度峰值、地面速度峰值等16种描述地震动强度的参数中,烈度识别正确率及相关性最好的两个参数分别是标准累积绝对速度和谱烈度。
The correlation between several strong ground motion parameters and seismic intensity was presented by the analysis of acceleration records obtained in three destructive earthquakes in California and Wenchuan earthquake by using the least squares method.The results indicate that among the sixteen strong ground motion parameters analyzed in this article,cumulative absolute velocity and spectrum intensity are the best two parameters with the largest recognition rate,which could be used to predict the instrumental intensity.
