摘要
为探究在海底地震动作用下海洋工程地质体的地震反应特征,基于中国南海岛礁场地钻孔资料和日本房总半岛沿海地区海底强震记录,通过土层地震反应分析结果讨论了地震动特征、场地条件对地震反应的影响。建立岛礁四类工程地质场地的一维土层模型,并讨论了其在浅源和中深源海底地震动作用下地震反应特征。研究结果反映了特殊海洋工程地质对海底地震动的场地反应特征,可对岛礁场地的开发建设提供参考。
In order to study the site effect of ocean engineering geology under ocean ground motion, several representative soil drilling data and Boso peninsula ground motions are selected in this paper, based on the seismic data and equivalent linearization analysis method, the effect of seismic characteristic and site condition on seismic response are discussed. The ocean engineering geology are divided into four types, and the physical, dynamic nonlinear parameter model are established. The seismic response of ocean engineering geology under ocean ground motions are discussed. The results of this study reflect the seismic response characteristics of the ground motion on the ocean engineering geology, it can provide reference for the development and construction of coral reef sites.
