[摘要] 针对核电站结构在地震中出现的一些问题，基于概念设计理念，对设计和加固改造核电站提出若干建议，包括：合理布局、多道设防、加强连接、明确简图、应用结构控制技术和振动损伤判别检测技术等等。还提出了若干具体做法，如：把安全壳等做成地下双层结构、将有关静定结构与构件改为超静定结构、分割结构体系使计算简图简单化、简化传力路径、调整相关结构质量与刚度、强化主结构弱化次结构、弱化连接避免耦联、调节布局改变结构振型以减小响应、采用隔振技术与阻尼技术、应用损伤识别与诊断技术等等。

Abstract: For problems appearing in the earthquake, some suggestions on design and retrofit of nuclear power plants were put forward based on concept design idea. The suggestions involves reasonable layout, multi-channel fortification, strengthening the connection, clear diagram, applying structure control technology and vibration damage detection technology etc.. Some concrete methods were also put forward, such as making containing vessel as a two-layer underground structure, changing the statically detenmnate structure to the statically indeterminate ones, simplifying calculating diagram by dividing structure system, adjusting the mass and stiffness of structure related, strengthening the main structure, weakening subordinate structure, optimizing vibration mode by adjusting the layout to reduce response, applying vibration isolation and damper technology, applying structural damage identification and diagnosis technology, and so on.
