5·12汶川大地震的震害资料表明,目前各级变电站主控楼等建(构)筑物的抗震能力较为薄弱,对位于地震频发区域的枢纽变电站采用隔震技术对提高主控楼的抗震能力很有必要。根据330kV临江变电站主控楼的结构特点,开展了主控楼隔震层的隔震支座选型与布置设计,并对主控楼隔震设计进行了有限元分析与验算。分析表明,合理采用隔震技术可有效降低主控楼的地震响应,达到了预期的设计目标。
5.12 Wenchuan earthquake damage data show that the current building at all levels such as control substation main building (structure) of the seismic capacity is relatively weak, the seismic substation located in the area of seismic isolation substation technology to improve the control building The seismic capacity is necessary. According to the structure characteristics of the main control building of 330kV Linjiang Substation, the design and layout of the isolated bearings of the main control building are carried out. The isolation design of the main control building is analyzed and verified by finite element method. The analysis shows that the rational application of seismic isolation technology can effectively reduce the seismic response of the main control building and achieve the expected design goals.
