预应力连续箱梁桥是目前混凝土桥梁的主要类型,此种结构类型的桥梁具有刚度大、不易形变、行车平稳等性能优势,但近年来关于此类桥梁的病害报道逐渐增多,其中以腹板裂缝最为常见。本文就结合笔者亲历浙江台州内某桥实例,分析造成现浇预应力连续箱梁施工过程中腹板裂缝的原因,并根据成因探讨相应的防治措施。 The prestressed continuous box girder bridge is the main type of concrete bridge at present. The bridge of this kind of structure has the advantages of great rigidity, not deformation, stable running and so on. But in recent years, the reports about the diseases of such bridges have been gradually increasing. The most common cracks. Based on the author’s experience of a bridge in Taizhou, Zhejiang Province, this paper analyzes the causes of web cracks during the construction of cast-in-place prestressed continuous box girder and explores the corresponding prevention and control measures according to the causes.
