预应力混凝土组合箱梁近年在高速公路工程得到极大的推广应用,从现场施工实践看,这种结构桥型在施工中容易出现一些质量通病或质量缺陷。本文从预应力混凝土组合箱梁的预制安装、预应力张拉和压浆及箱梁混凝土调平层施工三方面着手,将常见的质量通病或质量缺陷和防治措施及建议作了总结。 In recent years, the prestressed concrete composite box girder has been widely popularized and applied in the expressway construction. According to the site construction practice, this kind of structure bridge tends to have some common faults or quality defects during the construction. In this paper, three aspects of prefabrication of prestressed concrete composite box girder, prestressing and grouting and concrete leveling of box girder are discussed in this paper. Common defects, quality defects, prevention measures and suggestions are summarized.
