日本的产业结构正在由“重、厚、长、大”转向“轻、薄、短、小”,为此产业设施的抗震技术也正在发生着变化。为确保轻薄短小的代表性产业设施——电子计算机系统,半导体制造设备等免受震害,隔震技术的研究正在日益引起重视。所谓隔震技术是将被考虑隔震对象安置在特别的装置上,以求减 Japan’s industrial structure is shifting from “heavy, thick, long, and large” to “light, thin, short, and small”, and the seismic technology of industrial facilities is also changing. In order to ensure that the light and thin representative industrial facilities - computer systems, semiconductor manufacturing equipment, etc. from earthquake damage, the study of seismic isolation technology is increasingly drawing attention. The so-called seismic isolation technique is to place the considered earthquake-isolation object on a special device to reduce
