| 摘 要： | 介绍了带悬臂端的简支双T结构桥梁在缺乏设计及施工资料的情况下,对桥梁现状进行充分的调查检测,采用粘贴钢板法对其上部结构进行全面加固维修.通过全桥静载试验,测得该桥各控制截面的应力和挠度值,表明该桥上构经过全面维修加固后主梁的强度和刚度能满足加固设计荷载要求,各工况下相应部位砼和所粘贴钢板的实测应变数据分析表明,钢板和砼充分粘结,共同受力,粘钢效果良好.

| Abstract: | Lacking of the design and construction data but with a sufficient investigation and detection to the present statues of the bridge,an overall repairing of external strengthening with steel plates of the upper structures of one simply supported twin-T beams bridge with a cantilever is introduced.The values of stress and deflection of the key sections of the bridge are achieved through the dead load test of the whole bridge,showing that the strength and rigidity of the main beam can satisfy the request of the strengthening design load.The actual observation data provew that the steel plate and the concrete are sufficiently bond and jointly stressed,and the strengthening effect is good. |
