[摘要] 四川省江油市太白碑林太白楼为钢筋混凝土仿古建筑，汶川“5·12”大地震使其层3全部混凝土柱(28根)破坏。因采用置换法加固，设计一个20. 9m高的卸荷钢框架暂时将层3以上部分托起，待置换灌浆料达到设计强度后再将其放下。重点介绍了在卸荷钢框架的设计中如何考虑仿古建筑结构的特点及托换过程中余震的影响，为加固卸荷积累了经验。

Abstract: Taibai Steles' Taibai Building in Jiangyou city, Sichuan province, is a reinforced concrete antique building. All of 28 concrete columns in the third storey were damaged. In order to dismantle and replace the damaged columns, the method of the replacing grounting materials was adopted. So a 20.9m high decompression steel-frame should be designed to jack up the part above the third storey, after the replacing grounting materials reached the design strength then put them down the part above the tlurd storey. How to deal with the features of the antique building structure during the design of decompression steel-frame and the aftershocks' influences in the course of upbearing and replacement were focused on. It accumulates experiences for decompression of antique building.
