| 摘 要： | 文章以某大跨径连续刚构桥维修加固及荷载试验为例,结合荷载试验结果,分析该桥维修加固的效果。结果表明粘贴钢板和裂缝封闭对箱梁顶板纵向裂缝及腹板非结构性斜向裂缝的维修效果较好,但对箱梁底板横向受力裂缝的维修效果不明显,且结构整体刚度未得到改善,结论可为同类工程提供技术参考。

| Abstract: | Taking the repair and reinforcement and load test of a large-span continuous rigid frame bridge as the example,and combined with load test results,this article analyzed the repair and reinforcement effect of this bridge.The results showed that the pasting steel-plate and crack closing have the better repair effect for the vertical cracks of box-girder roof plate and the non-structural diagonal cracks of web plate,but the repair effect for the transverse forced crack of box-girder bottom plate is not obvious,and the overall structure stiffness is not improved,thus the conclusions can provide technical reference for similar projects. |
