摘要
在乌江特大桥边跨合龙段施工时,提出一种利用前支点挂篮作为支撑平台和在过渡墩上设置支架进行边跨合龙段施工的方法,并给出其总体施工工艺流程;在分析梁体温度效应基础上,采取一系列措施避免了温度引起新老混凝土接触面相互运动,造成拉应力的产生而影响合龙质量。
In construction of Wujiang Bridge side span closure,this paper proposed a construction method using the front fulcrum hanging basket as the supporting platform and setting up the bracket on the transition pier,and introduced its construction process. Based on the analysis of the temperature effect of the girder,a series of measures were adopted to avoid interaction between new and old concrete contact surfaces.
