摘　　要：隔减震加固是优于传统加固的新技术。简述了隔减震技术在既有工程加固中的应用现状及其基本原理;提出了隔震技术和减震技术各自对应的地震作用调整系数,并结合加固项目的实际情况得出较为合理的加固方案;考虑了采用隔震和黏滞阻尼器减震技术时对应支座和阻尼器数量及参数的确定原则及方法。实践证明,该方法在实际加固工程应用中起到了较好的指导作用。The technology of damping and isolation is superior to traditional reinforcement technology. Firstly, the application status and principles of the technology of damping and isolation in the existing engineering reinforcement were described. Then,the seismic action adjustment coefficients were proposed for the isolation and damping technology,respectively. And the optimum reinforcement scheme was selected according to the actual situation of the reinforcement project. Finally,the principles and methods for determining the number and parameters of the bearings and dampers when using the technolgy of isolation and damping device were considered. It is proved that this method has played a guiding role in actual reinforcement engineering application.
