【摘要】 以某千兆瓦级压水堆核电站反应堆厂房结构为对象,研究了考虑土-结构动力相互作用的硬土场地条件下地基土动态剪切模量的变化对楼层反应谱计算的影响,定量分析了厂房结构楼层加速度反应谱对地基土动态参数变化的敏感性,从而为评估类似硬土场地条件下核反应堆厂房结构抗震安全性提供了一种可供参考的计算方法。更多还原

【Abstract】 In this paper, against the reactor building of a 1000MW Pressurized Water Reactor (PWR) nuclear station, the influence of the change of dynamic shear modulus of foundation soil on the floor response spectra of nuclear reactor building on a site of hard soil is investigated by considering soil-structure interac- tion (SSI), and the sensitivity of the floor acceleration response spectra of the reactor building to the change of dynamic parameters of foundation soil is quantitatively analyzed, which may provide a reliable method and an important reference to evaluate the anti seismic safety of nuclear reactor buildings on similar sites of hard soil.更多还原
