INFLUENCE OF DIFFERENT TYPES OF ISOLATION BEARINGS ON ISOLATION PERFORMANCE OF NUCLEAR ISLAND PLANT

摘要

摘要: 以某百万千瓦级压水堆核电厂核岛厂房为研究对象，采用核岛筏板基础的整体隔震技术方案，对比分析了在不同周期地震动下分别采用三种常用基底隔震支座类型（铅芯橡胶支座、滑动支座、三重摆摩擦支座）核岛厂房的地震响应，探讨了上述结构考虑土-结构相互作用（SSI）效应的楼层加速度反应谱。分析结果表明：三重摆摩擦支座在短周期地震动下的隔震性能优于其他两种类型的隔震支座。铅芯橡胶支座可以满足不同周期地震动下的隔震性能要求。基于均质地基土的影响分析，非隔震结构的SSI效应影响明显大于隔震结构的，隔震结构的SSI影响在5%以内。采用滑动支座、三重摆摩擦支座的隔震结构考虑SSI效应时的楼层反应谱在低频阶段不能完全被不考虑SSI效应时的楼层反应谱所包络。

Abstract: Taking the nuclear island plant of a million kilowatt PWR nuclear power plant as the research object, using the overall isolation technical scheme of nuclear island raft foundation, the seismic response of nuclear island plant with three common types of base isolation bearings, including multi lead-core rubber bearing(MLRB), eradi quake system bearing(EQS), triple friction pendulum bearing(TFPB), was compared and analyzed under different periods of ground motions. The floor acceleration response spectrum of the above structure considering the effect of soil-structure interaction (SSI) was discussed. The analysis results showed that the isolation performance of TFPB under short period ground motion was better than that of the other two types of isolation bearings. The MLRB could meet the requirements of isolation performance under different periodic ground motions. Based on the influence analysis of homogeneous foundation soil, the SSI effect of non-isolated structure was significantly greater than that of isolated structure, and the SSI effect of isolated structure was less than 5%. The floor response spectrum of isolated structure with EQS or TFPB considering SSI effect could not be completely enveloped by the floor response spectrum without considering SSI effect in low frequency stage.
