| 摘 要： | 某刚架拱桥由于桥面板开裂较严重 ,造成桥的整体刚度下降 ,承载能力和安全性降低。通过增加桥的横向联系 ,置换全部桥面板并采用钢纤维混凝土浇筑面层 ,对拱顶部位粘贴玻璃纤维 -芳纶纤维混合织物进行加固。加固前和加固后的荷载试验表明 ,采用这种加固方案提高了桥的整体刚度和承载力 ,达到了预期的效果

| Abstract: | Bearing capacity and security decreased due to the loss of integral rigidity of rigid frame arch bridge caused by the crack of bridge deck concrete.This paper describes a example of strengthening bridge by increasing transverse connection,replacing whole bridge deck,using the steel fiber reinforced concrete as surfacing material and bonding glass\|kev fiber reinforced plastic on the vault.The test carrying out before and after strengthening shows the method is effective for enhancing integral rigidity and capacity of bridge. |
