近断层水平速度峰值衰减关系的比较与分析
|
摘要
地震动特征参数的衰减关系可为工程结构地震危险性分析以及设计提供依据,因此国内外较多学者开展了近断层地震动特征参数衰减关系的研究,尤其是近几年,还出现了一些水平速度峰值衰减关系的研究.但由于采用的地震记录不同,考虑的影响因素也存在差异,所以不同学者得到的衰减关系也有区别.因此,在应用时,采用哪种衰减关系更为合理也就成为一个有待解决的问题.在此选择了近些年出现的具有一定代表性的水平速度峰值衰减关系,比较了各速度衰减关系计算值以及实际记录值的差异,推荐了可供实际参考的水平速度衰减关系模型.
Since the attenuation relationship of earthquake dynamic characteristic parameters can provide reference for earthquake risk analysis and design of engineering construction,more and more scholars at home and abroad study on attenuation relationship of earthquake dynamic characteristic parameters.Especially in recent years,some horizontal velocity peak value's attenuation relationships have occurred.Since the applied earthquake records are different and the considered influencing factors are different,the attenuation relationship got by different scholars is different.So which relationship's use being more reasonable becomes a problem to be solved.In this paper,the representative horizontal velocity peak value's attenuation relationship appeared in recent years are selected,the calculation results of each velocity's attenuation relationship and the difference of actual records are compared,the model of horizontal velocity attenuation relationship is recommended for practical reference.
