摘　　要：高层建筑结构一些楼层大幅度增加使用荷载后,结构加固改造将涉及诸多复杂技术问题。本文通过一工程实例介绍了板加固后的新旧混凝土界面抗剪、板顶负筋锚固,梁加固纵筋锚固、抗剪箍筋的设置方法,节点的处理,抗裂等技术措施,可为同类工程实践提供参考。The live load of some floors increased largely so,the high-rise building should be reinforced and reconstructed.Some complicated technical problems should be overcome during design.The technology methods including anti-shearing force in the interface of concrete members, anchorage of the top reinforcement of the slabs,anchorage of reinforcement of beams,arrangement of the stirrup bar of beams,node,and anti-cracking are mentioned. It provides reference for other reinforcement engineering,
