连续箱梁裂缝的防治方法探讨连续箱梁裂缝的防治方法探讨 摘要：预应力混凝土连续箱梁桥在近几十年来以其结构刚度大、行车平顺性好、伸缩缝少和养护简单等一系列优势而进展迅速，在这一过程中，我国的预应力混凝土连续箱梁桥在设计、施工、运营以及养护管理等方面不到位而导致了一系列桥梁病害
桥梁病害中尤以箱梁腹板斜裂缝的产生和进展较为普遍，而且易影响桥梁的正常运营以致承载能力的破坏
因此，分析斜裂缝的产生机理和影响因素，进而为病害桥梁进行有效的维修加固务必引起足够的重视

Especially in the box girder bridge diseases in the redesign of the cracking of the development and
