摘要
隔震技术是目前公认有效的地震控制技术,而地震的不确定性依然是核电站抗震安全的巨大挑战。首先,针对AP1000新型非能动型核电站结构设计了包括安全壳、屏蔽厂房、附属厂房在内的隔震试验模型。其次,对隔震模型进行了模拟振动台试验,试验结果表明,隔震技术能够有效降低核电结构上部的地震响应。最后,对核岛厂房应用隔震技术进行了讨论,表明了隔震装置的应用能够实现设计能力翻倍的目标。
Isolation technique is widely recognized as an effective seismic control technology,and the uncertainty of the earthquake is still a big challenge seismic safety of nuclear power plants. Firstly,based on the stucture of the new AP1000 passive design of nuclear power plants,isolation test model of including containment,shielding the plant,and the subsidiary plant are established. Secondly,the isolation model is simulated by shaking table test. The test results show that isolation technology can effectively reduce the nuclear structure of the upper part of the response. Finally,the application isolation techniques of nuclear island plant are discussed. It is concluded that the application isolation device can be designed to achieve the goal of doubling the capacity..
