摘　　要：通过加固工程实例介绍了大跨度楼板板面有墙荷载,楼板承载力不足时,采用板面浇筑混凝土叠合层,板底粘贴碳纤维布的加固方法。对该大跨度楼板进行加固处理后,后期使用荷载作用下的挠度进行了计算,找出加固时需要进行顶升处理的楼板,针对现场情况提出了一种简单、易行的顶升处理方法。When the bearing capacity of long span floor slab has a certain lack under the load of wall on it,a method with pouring concrete composite layer beyond the floor slab and bonding CFRP（Carbon Fiber Reinforced Polymer） sheets beneath the floor slab has been adopted in an engineering case.The deflection of the long span floor slab after strengthening under service load is calculated.Then the floor slabs needing lifting in strengthening are confirmed,and a simple and practical method for lifting is brought forward.

关 键 词：加固 大跨度楼板 叠合层 碳纤维布
