用于核工程地震安全性评价的中小地震水平向加速度反应谱衰减关系研究
Study on Attenuation Relationship of Horizontal Acceleration Response Spectrum of Moderate-small Earthquakes for Seismic Safety Evaluation of Nuclear Engineering
【摘要】 利用美国西部的中小地震记录对基岩场地条件下的中小地震水平向地震动多阻尼加速度反应谱的衰减关系进行了初步研究,并分析了震级与距离对中小地震水平向地震动加速度反应谱衰减规律的影响。
【Abstract】 On the basis of the recordings obtained during the moderate-small earthquakes in the western United States,this paper studies the attenuation relationships of multi-damping acceleration response spectra of horizontal ground motion for the moderate-small earthquake.The paper also analyzes the influences of magnitude and hypocentral distance on the attenuation law of horizontal ground-motion acceleration response spectrum of moderate-small earthquakes.
