文章通过对晋济高速公路七甲坡一号大桥采用悬臂浇筑法施工桥梁上部结构施工控制挠度等问题进行了主要论述。提出了如何根据桥梁的结构安全和最终线型来确定立模标高,以及怎样在施工中快速有效地确定和预计下一块段的立模标高,对施工有一定的指导作用。
This paper mainly discusses the construction control deflection of the superstructure of cantilever construction of Qijiapo No.1 Bridge in Jinji Expressway. It is proposed how to determine the vertical elevation of the bridge according to the structural safety and the final linearity of the bridge and how to determine and estimate the vertical elevation of the next block quickly and effectively in construction so as to guide the construction.
