摘要

摘要: 核电站安全壳的安全性和完整性在建造运营期间必须要得到保证，尤其是对于强烈地震和飞机撞击等超设计基准事故。基础隔震作为一种能有效降低上部结构地震响应并防止结构破坏的典型隔震措施，在未来的核电站设计建造中备受关注，因而在核电站隔震系统的建造设计时应考虑大型商用飞机撞击的影响。该文基于CPR1000核电站安全壳，在底板下侧布置了不同型号的高阻尼橡胶隔震支座，从结构的隔震率（DAR）、最大水平位移和加速度反应谱，对安全壳在强烈地震作用下的隔振性能进行了综合分析。并结合采用荷载时程法以A320商用飞机撞击荷载为例进行飞机撞击核电站安全壳的分析，着重从飞机撞击后的振动衰减过程的振动特性以及飞机撞击诱导振动的加速度反应谱的分析结果对具有隔震构造的安全壳振动规律进行了分析。

Abstract: The safety and integrity of nuclear power plant (NPP) containments must be guaranteed during the plant's lifecycle, especially in the event of severe earthquake and aircraft crashes. Base isolation, as a seismic isolation measure which can effectively reduce the seismic responses of the superstructure and prevent structural damage, draws much attention in the design and construction of nuclear power stations both at present and in the future. Therefore, it is necessary to consider the impacts of large commercial aircraft on the containment in the design of isolation systems for nuclear power plants. This paper studied and analyzed the isolation performance from decreasing amplitude ratio (DAR) and the maximum horizontal displacement of the containment on the basis of the CPR1000 containment with different types of high damping rubber bearing installed under the base mat. Moreover, it also conducted safety assessment of the containment with seismic isolation combined using the load time history method with taking the impact load of A320 commercial aircraft as an example. The primary results of the aircraft impact focused on the vibration characteristics of the vibration attenuation process and the acceleration response spectrum of the aircraft impact induced vibration processes.
