| 摘 要： | 建立合理的地震烈度与地震动参数之间的对应关系,在工程抗震及烈度速报中有着十分重要的作用,文中以美国加州3次破坏性地震和我国今年来6次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.经统计发现,在地面加速度峰值、标准累计绝对速度等12种描述地震动强度的参数中,各种参数在...

| Abstract: | 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 six earthquakes in China using the least squares method.The results indicated that among the sixteen strong ground motion parameters analyzed in this article,the recognition rates of twelve ground parameters in different seismic intensityies are absolutely different,so the model of multiple element regression b... |
