摘要
以在建的鲍家洲汉江特大桥使用的三角挂篮为例,阐述了三角挂篮结构,进行了挂篮变形理论建模计算、挂篮预压试验结果分析以及挂篮变形的监测,并对若干个悬臂浇筑节段的挂篮变形值进行对比分析,为该桥悬臂施工的线形控制提供依据。
The structure of the triangle hanging basket is expounded based on the Baojiazhou Han- jiang Bridge under construction in this paper. The theoretical calculation of the deformation, the analysis of the preloading test and the monitoring of the deformation of the triangle hanging basket are illustrated. The deformation analysis of the triangle hanging basket of several cantilever segments is made, which provides the basis for the alignment control of the cantilever construction.
