摘　　要：针对核电站传统结构在服役期间可能出现的地震破坏,应用建筑结构隔震减震技术,将AP 1000核电站的非能动安全理念推广到结构抗震领域,提出了屏蔽厂房基础隔震-调频质量阻尼(BIS-TMD)新型结构,大幅度地提高了屏蔽厂房的抗震安全。基于屏蔽厂房各部分的功能要求,修改了屏蔽厂房各部分的连接方式,在增加附加质量很小的情况下,实现了本新型结构。基于AP 1 000基础隔震结构的研究成果,构建了本新型结构的参数优化模型,给出了TMD支座的选型参数,研究了本新型结构的减震机理。通过与传统结构、基础-隔震结构和TMD结构等比较,表明了本新型结构综合了BIS和TMD的优点,能够很好地抵御地震大小和频谱、重力水箱水质量、TMD支座和BIS支座力学性能等因素变化对减震效果的影响;具有显著的减震效果,稳定的抗震鲁棒性和良好的场地适用性,能够很好地满足核电站抗震安全的要求。For seismic damage that may occur during the service of traditional structures of nuclear power plants,seismic isolation technology of building structures is used to promote the passive safety concept of AP 1 000 NPPs to the field of structural earthquake resistance,and to propose a new type of structure used for shield building which is called base isolation-Tuned mass damping（ BIS-TMD）. This new structure has greatly increased the seismic safety of the shield building. Based on the functional requirements of each part of the shield building,the connection method of each part of the shield building was modified,and this new type of structure was realized with a small additional quality. Due to the research results of the base-isolated structure of AP 1000,a parameter optimization model of the new structure was constructed,the selection parameters of the TMD support were given,and the damping mechanism of the new structure was studied. Comparing with the traditional structure,the BIS structure and the TMD structure,it indicates that this new structure combines the advantages of BIS structure and TMD structure,and can well resist the changes of the size and spectrum of earthquake,water quality of gravity tanks,and the mechanical properties of TMD support and BIS support on the damping effect. Meanwhile,this new structure has significant absorption effect,stable seismic robustness and good site suitability,and can well meet the seismic safe-ty requirements of nuclear power plants.
