摘要:核岛厂房隔震有别于传统的抗震设计,国外已有成功应用隔震技术的运行核电厂;但我国对核电厂
隔震技术的研究相对较少,日本福岛核电厂超设计基准事故发生之后,隔震技术日益受到各方关注。以某
核电站安全壳隔震方案为例,利用有限元 ANSYS 软件,建立核岛结构隔震计算仿真模型,对安全壳厂房
结构进行动力时程分析,重点比较采用隔震技术后安全壳的地震响应规律,总结隔震技术的优点。

Abstract: Nuclear island buildings seismic isolation device is a passive active control system, which is different
from traditional anti-seismic structure system. Seismic isolated nuclear island building structures systems are
applied in some foreign NPPs, while it is studied seldom in China. Many people pay attention to seismic isolated
structure gradually after the extraordinarily severe beyond design-basis nuclear accident at Fukushima nuclear
power plant in three dimensional finite element model of the nuclear island building structures is built
based on some typical nuclear island isolation structure formation by using ANSYS program. The response
spectrum and time-history response analysis are put emphasis on evaluting the seismic dynamic response laws of
concrete containment.
Key words:Concrete containment ;nuclear island; isolation; time-history response analysis
