【摘要】 首先对减隔震技术的概念、原理等作了一定的介绍,并通过与传统的利用结构自身强度抵抗地震作用方法的比较,说明了减隔震技术在减小结构的地震反应、工程造价方面的优越性。在对几座典型的减隔震桥梁介绍基础上,表明了减隔震技术在一些桥梁结构抗震设计或加固中的应用情况与所取得的良好的抗震性能。阐述了目前减隔震技术研究的情况及今后需要进一步研究的问题,为我国从事相关工作的工程人员和研究人员提供一点参考。更多还原

【Abstract】 First,the conception and principle of isolation technology are introduced,and then the superiority of the isolation technology is explained,the seismic response and project cost can be reduced by the isolation technology in comparion with the traditional design methods which are resistant to the action of earthquake by self-strength.Based on the introduction of several isolated bridges,it is demostrated that the seismic isolation has been more and more widely used in the seismic design and aseismic strengthening in bridge engineering,and it has great seismic performance.Finally,the current studies on the isolation technology and the furture questions are elalorated,which may be provided a good reference for engineers and researchers engaging in this field.更多还原
