| 摘 要： | 采用Midas软件,计算了20 m跨双曲三铰拱桥在各种荷载工况作用下的内力状况,通过内力计算结果找到了结构破坏的原因.采用粘贴钢板法对该桥进行了加固,介绍了该法加固双曲拱桥的具体操作方法.对加固后的桥梁进行了荷载试验,比较了已加固跨和未加固跨结构的位移情况.试验结果表明加固效果良好.

| Abstract: | Using finite element software Midas/Civil,established a feasible plane truss model; and calculated the distribution of internal forces under various of loads cases of this double-curved triangular arch whose span is twenty meters' long and also find out the destructive reason. Fastened steel plate method was used to retrofitting this bridge,At last,a loading test on this bridge is carried out,and the results of loading test show that the effect of strengthening is remarkable and the bearing capacity of the ... |
