预应力混凝土空心板桥加固设计

On consolidation design for prestressed concrete hollow slabs

针对某空心板桥部分截面极限承载力不满足规范要求,需予以补强、加固的情况,提出了因地制宜的改造加固方案,并详细介绍了粘贴钢板加固的计算方法,以期指导该桥加固工作。

According to some section of some hollow slabs which should be strengthened and consolidated because its limited loading capacity can not meet the regulation,the paper points out the reconstruction and consolidation scheme according to the various locations,and introduces the calculation methods for the consolidation by the bonding steel plate,so as to direct the consolidation of the bridge.
