| 摘 要： | 针对大亚湾核电站继电器机架橡胶减震器因老化破裂而影响机架的抗震性能、日常运行和维修等问题而提出支撑改造方案,采用谱分析法对改造前后的各种支撑结构进行初步力学分析.比较了大亚湾继电器机架改造前后支撑的抗震性能,以及大亚湾和岭澳两种继电器机架支撑结构在同一地震载荷作用下的力学响应,为大亚湾核电站继电器机架支撑的加固改造提供参考.

| Abstract: | Spectrum method was used for aseismatic analysis of relay frame support including rubber dashpot,Z support and U support reconstructed of Daya Bay Nuclear Power Plant,and relay frame support of Ling'ao Nuclear Power Plant.The aseismatic capability was compared before and after relay frame reconstruction under the same seismic load.It provides a reference for relay frame support's renovation of Daya Bay Nuclear Power Station. |
