为探讨隔震技术在核电工程的应用,对某核电站应急指挥中心进行隔震设计及相应分析:对隔震层的方案进行详细的阐述,包括隔震支座的选型及布置;建立应急指挥中心的有限元模型并进行非线性动力反应分析,探讨结构在地震作用下的动力特性、加速度反应和位移反应。分析表明:通过隔震层的变形吸收地震的能量,可以显著降低上部结构的地震反应,结构的减震效果达到70%左右,隔震效果明显,提高了应急指挥中心的抗震裕量,可以有效保护应急指挥中心的人员、设备和系统的安全,从而提升核电站震后应急能力。分析研究成果对隔震技术在核电领域的推广应用有一定的积极意义。
In order to discuss the application of isolation technology in nuclear power project, the design and analysis of the isolation center of a nuclear power station emergency command center are described in detail. The solutions of isolation layer are elaborated in detail, including the selection and arrangement of isolation bearings, the establishment of emergency command Center of the finite element model and nonlinear dynamic response analysis to explore the structure under the action of earthquake dynamic properties, acceleration and displacement reaction. The analysis shows that the seismic response of the superstructure can be significantly reduced by absorbing the energy of seismic isolation through the deformation of the isolation layer. The damping effect of the structure reaches about 70% and the seismic isolation effect is obvious, thus improving the earthquake resistance margin of the emergency command center and being effective Protect the safety of personnel, equipment and systems in the emergency command center, so as to enhance the post-earthquake emergency response capability of nuclear power plants. Analysis and research results on seismic isolation technology in the field of nuclear power to promote the use of a certain positive significance.
