摘　　要：为保护我国馆藏浮放文物,基于文献查阅的方法,本文总结论述了我国博物馆文物的存放方式和地震中的破坏形式,指出了传统防震措施的局限性;同时着重探讨了国内外浮放文物隔震技术的现状,并归纳指出了楼层反应谱的计算方法及其影响因素,以及指出了摩擦系数、宽高比等对浮放文物运动状态的影响,且较为详细地介绍了隔震装置的国内外研究现状。同时,指出国内仍需在浮放文物振动控制技术标准和设计方法方面做进一步研究。To protect domestic museum cultural relics,the preservation methods and the damage forms in the earthquake were studied based on literature results.The limitation of the classical aseismic measures was showed in the paper.Meanwhile,the situation of isolation technologies for free-standing cultural relics at home and abroad were investigated.In this part,the computing methods and influence factors of floor response spectra were presented,as well as the influence of some parameters such as friction coefficient and width height ratio on the motion state of free-standing cultural relics.Also the research status at home and abroad of isolation devices was instructed detailedly.The standard of vibration control technology and design method of free-standing cultural relics at home need to be further studied.
