摘要
三维隔震对保护核电厂结构和内部设备设施安全具有重要意义。首先,设计了一种三维隔震控制系统,该系统包括水平隔震层和竖向隔震层,在竖向隔震层中设置抗摇摆装置以达到控制结构摇摆反应。其次,对三维隔震模型进行了振动台试验验证,振动台试验结果表明,该系统能有效减小上部结构地震响应。最后,对核岛厂房采用三维隔震技术进行了讨论,分析了强震作用下核岛厂房三维隔震结构反应特征。
Three-dimensional( 3D) seismic isolation technologies are important in protecting nuclear power plant and equipment facilities safety. Firstly, the paper designed a new 3D isolation system, which includes horizontal isolation layer and vertical isolation layer, and the rocking suppression devices were installed in the vertical layer to control the rocking motion of upper structure. Secondly, the paper conducted the shaking table tests for 3D isolation structure model. The shaking table test results show that the 3D isolation system can effectively reduce the seismic response of the upper structure. Finally, the paper disused the nuclear island structure by adopting the 3D isolation technique, and analyzed the response characteristics of the nuclear island structure under strong seismic action.
