摘 要: 根据高新大桥的检测结果,采用"粘贴碳纤维布新技术"结合"高渗透性环氧树脂灌胶封闭裂缝技术"对位于通航孔受损较为严重的主梁梁肋进行了加固设计与施工.该项新技术既缩短了施工周期,又解决了施工中不中断交通的难题. Based on inspect and test result of Gaoxin-bridge, the strengthening design and construction of girder with relatively severe damage of navigation span of the brideg are carried out by combining new technology of CFRP ( carbon fiber reinforced polymer) strengthening with the technology of obturating cracks using epoxy resin with high penetrability. The construction period is shortened and uninterrupted traffic during construction is maintained due to the new technology.
