[摘要]  位于河南省焦作市境內(nèi)的云陽(yáng)河橋，因其設(shè)計(jì)標(biāo)準(zhǔn)偏低，其箱形梁體出現(xiàn)了多種病害。經(jīng)多種加固方案進(jìn)行比較，確定采用預(yù)應(yīng)力碳纖維板進(jìn)行加固。鉸式波形錨張拉碳纖維板的施工工藝，因其夾持和錨固碳纖維板可靠，張拉方法簡(jiǎn)單，易于施工，是板梁橋、箱梁橋加固的一種較先進(jìn)的技術(shù)。云陽(yáng)河橋加固采用了鉸式波形錨的預(yù)應(yīng)力加固的技術(shù)，本文對(duì)這一加固工程進(jìn)行了介紹。

Abstract: Because of its low design standard, the box beam body of Yunyanghe Bridge located in the Henan Jiaozuo has appeared a variety of diseases. The bridge structure strengthened with prestessed CFRP plat is selected by compared several strengthening plans. Because of the advantages of more reliable to clamp and anchor CFRP, easier to tension and construct, the anchorage systems of prestressed CFRP plat is one more advanced technology to reinforcing plate girder bridge and box girder bridge. This technology was applied to YunYang Bridge reinforcement project, and this paper introduces the reinforcement project.

Keywords: Bridge structure strengthened; CFRP; Prestressed; Box girder bridge; hinged anchor
