摘　　要：通过介绍隔震技术的发展与研究现状,分析了隔震机理与隔震体系的基本特性。针对我国广大村镇地区抗震设防事业发展现状,提出将砂-橡胶粒隔震垫层作为一种隔震材料用于基础隔震中去。以砂-橡胶粒隔震垫层作为研究对象,通过理论分析和振动台试验,研究砂-橡胶粒隔震垫层的减震效果。实验结果表明,隔震垫层加速度折减系数在0.212~0.592,位移放大系数稳定在1.01~1.39;砂-橡胶粒隔震垫层改善了上部结构的动力特性,具有明显的隔震效果,适合在村镇推广使用。By reviewing the development and research of seismic isolation techniques for civil engineering structures,this paper investigates the control mechanism of the isolation and the fundamental characteristics of isolation system.In view of the development status of earthquake fortification of the buildings in villiage of our country,the sand-rubber vibration isolation cushion is proposed as a kind of seismic isolation material in base isolation in building.The damping effect of the sand-rubber vibration isolation cushion is investigated by theoretical analysis and shake table test on sand-rubber vibration isolation cushion.The test result show that the acceleration reduction factor of isolation cushion was between0.186~0.592,and the displacement amplification factor was between1.02~1.39;The superstructure’s dynamic property was improved anda good seismic reduction effect was exhibited due tosand-rubber vibration isolation cushion,which is suitable to be used in rural areas.
