核电站结构隔震研究进展

基底隔震已经大量应用于一般民用建筑中,被认为是在剧烈地震中保护建筑物最具发展前景的技术之一,但对于核电站这类特殊的建筑物应用较少,且研究比较薄弱。介绍了核电站水平及三维隔震装置的研发及性能测试,概述了核电站隔震系统抗震性能的研究进展和核电站隔震设计规范,指出了在核电站中应用隔震技术还有待解决的问题,对今后核电站隔震的研究提出了一些建议。

State of the Art of Nuclear Power Plant Using Base Isolation

The base isolation has been widely used in general civil building, which is considered as one of the most promising technology to protect building from violent earthquakes. But it is seldom used in this special structure of nuclear power plant, and the research on it is rather weak. This paper introduces the research and development as well as the performance test of nuclear power plant horizontal and three-dimensional seismic isolation devices, and summarizes seismic performance research advances about nuclear power plant seismic isolation systems. Finally, seismic design code for nuclear power plant is presented, furthermore, some suggestions on nuclear power plant isolation for future research are put forward.
