【摘要】 基于黏弹性动力人工边界理论,考虑结构—地基动力相互作用,分别分析了系统频率与楼层反应谱,揭示了成层地基对核电厂竖向动力特性的影响。计算结果表明,核电厂竖向反应谱更易受成层地基影响,该方法可供核电工程借鉴。更多还原

【Abstract】 Based on the theory of viscoelasticity dynamic artificial boundary,this paper analyzes the system frequencies and the floor response spectrum by considering the interaction of soil and structure.The influence of layered foundation on vertical dynamic response spectrum of nuclear power plant is investigated.The numerical results reveal that the vertical response spectrum of nuclear power plant is more sensitive to layered foundation.Thus,this method has certain referential value for nuclear power plant project.更多还原
