变截面箱梁挂篮施工质量控制探讨

Discussion on the quality control of variable cross-section box-girder cradle construction

结合汉江特大桥主桥变截面箱梁挂篮施工,从挂篮的质量要求、悬浇混凝土的质量控制及施工中质量问题的处理等方面对预应力混凝土连续刚构变截面箱梁桥施工质量的控制进行了探讨,为类似工程施工提供指导。

Combining with the main bridge variable cross-section box-girder cradle construction of super large bridge in Hanjiang, the construction quality control of prestressed concrete continuous rigid frame variable cross-section box-girder bridge was discussed from the quality require- ment of cradle, the quality control of cast-in-place concrete and the treatment of quality problems in construction, which can provide guide for similar engineering construction.
