组合梁斜拉桥桥面板湿接缝施工探讨

Discussion on Wet Joint Construction of Deck Slab for Combined Beam Cable-stayed Bridge

桥面湿接缝混凝土施工面积大,作业时间跨度长,防止裂缝的产生是项目施工解决的重点问题。该文以某工程为例,对浇筑试验段,进行体外试验,完全模拟现场的施工环境,总结出施工中控制的关键因素,进而在实际的湿接缝浇筑中加以实施,取得了良好的效果。

It is an important problem to solve the cause of cracks in the project construction because of the deck wet joint concrete construction area large and the construction time long.Taking a project as an example,the article describes the in-vitro-tests of the poured tested section and the construction environment of fully simulated field,and sums up the key control factors in the construction so as to implement in the practical wet joint pouring and to obtain the good effect.
