摘要 预应力混凝土箱梁因具有良好的受力性能而在桥梁工程中得到广泛应用。箱梁桥的抗裂是工程设计、施工和使用维护过程中普遍关注的问题。该文将裂缝分为荷载裂缝和非荷载裂缝两大类,分析了各种裂缝的形成机理、特性和主要影响因素,提出了箱梁桥裂缝防治的主要措施。从设计理论、预应力和结构试验等方面指出了当前预应力混凝土箱梁桥抗裂研究中存在的主要问题。为今后进一步研究预应力混凝土箱梁桥的抗裂性能提供了新思路。 Prestressed concrete box girder is widely applied in bridge structures for its favorable mechanical performance.The cracking prevention in concrete box girder bridges is universally concerned in the stages of structural design,construction and service.Cracks in prestressed concrete box girder are classified into two categories,load-related cracks and load-unrelated cracks.The formation mechanism,properties and the main influential factors of cracks are analyzed.The major crack prevention measures are also discussed.In conclusion,many crucial problems about crack prevention research in prestressed concrete box girders are pointed out from the aspects of design theory,prestress loss evaluation of strands and experimental investigation.Some new suggestions are given for the further study of crack prevention in prestressed concrete box girder bridges.
