浅议日本核电站隔震技术的研究和应用

Research and Apply of Nuclear Power Plant Seismic Isolation in Japan

隔震在民用建筑领域的应用越来越多,是减震抗灾的有效手段之一。中国核电站的厂址加速度比国外某些核电站的厂址加速度大,对于引进的核电站需要降低其地震响应。日本的地震活动比较活跃,在隔震方面的研究和应用比较多。日本在多年研究的基础上,选择了两种快堆核电站的三维隔震装置,制作缩比例模型完成振动台试验。试验结果表明两种隔震装置均适用于快堆核电站。

Seismic isolation is applied more and more in the civil architecture and it is one of the valid measurements of shock absorption and against disasters. The cites acceleration of China nuclear power plant is bigger than the foreign nuclear power plant. It is necessary to decay the nuclear power plant response. Research and apply of nuclear power plant is much because the Japan earthquake is active. Based on many year researches, the two 3-dimension base isolation devices of Fast Breeder Reactor are selected and scaling models are made and tested. Judging from the results of the shaking table test, the developed 3-D base isolation devices are applied to a nuclear power plant.
