隔震系统回顾reviews of development in base isolationThe idea of base isolation dates back to the latenineteenth century, but the application of generalized ideaof base isolation has even longer history. The sticky ricemixed lime was used in the Forbidden Palace to form theflexible isolated layer. However the theory and applicationof modern base isolation just began in the 1970s and arewidelyused recently基础隔震的概念早在19世纪已有人提过，广义的隔震方案则更是源渊流长，如北京故宫就设有糯米加石灰的柔性减震支座层：现代的基础隔震理论和实践开始于上世纪70年代，应用较为广泛

1.早期隔震技术EarlySeismicIsolationTechnology河合浩藏的“地震时不受大震动的结构”右图是1891年日本的河合浩藏的“地震时不受大震动的结构”其隔震思路是在地基上并排铺设剖面一了数层圆木，并且把建筑物周围混凝土挖空，从而地震时可对上部建筑立面圆木层起到隔震作用In 1891 Kawai Hirohide proposed the“structure withoutgreat vibration under earthquake". The logs is used betweenthe upperstructureandbasetoisolatethebuildingfromtheground motion under earthquake

Seismicallyisolatedstructuresproposed byJ.A.CalantarientsJ.A.Calantarients于1909年提出的隔震结构(Base-isolated滑石building）方案。这种隔震结构滚轴在建筑物结构与基础之间用滑石层隔开，地震时建筑物可以滑动。The first patent application for seismic isolation wasgranted to Mr. J.A. Calantarients in 1909. His idea was toinstall a sliding layer between the building and itsfoundation to allow the building to slide during anearthquake. Thusly, the energy transmitted to the buildingitselfisreduced
