[摘要] 以汶川地震后剑南春总部办公楼的新建工程和都江之春1#楼加固工程作为案例，介绍隔震技术在灾后重建中运用的工程实例。通过对比传统抗震方案和基础隔震方案的抗震效果，分析了采用隔震技术对结构的层间剪力和自振周期等方面的影响。结果表明，采用隔震技术可延长结构自振周期，显著降低上部结构的地震反应，减轻地震作用对主体结构的损坏，有效提高建筑的抗震性能，从而满足建筑抗震设计规范的要求。

Abstract: The application cases using seismic isolation technology in reconstruction after the Wenchuan Earthquake were introduced, taking Jiannanchun office building construction project and Dujiangyan reinforcement project as examples. By comparing the traditional scheme and base isolation scheme, the influence of using seismic isolation technology on interfacial shear stress and natural vibration period was analyzed. The results show that using seismic isolation technology can extend the natural vibration period of the structure, reduce the earthquake response of upper structure and the damage on main structure, effectively improve the seisnuc properties, so as to meet the requirements of the code for seismic design of buildings.
Keywords: Wenchuan Earthquake; post-disaster reconstruction; seismic base isolation
