摘要
主要介绍了在桥梁悬臂施工中挂篮反拉加载试验,进行了挂篮建模与施工分布荷载理论计算,通过对实测结果分析得出反拉加载能够较好模拟挂篮实际受力情况,比常规挂篮加载试验能大幅节省时间、机械及人工等费用的结论。
The paper mainly introduces the loading tests of hanging basket pull in the cantilevel construction of bridges, undertakes the calculation for the hanging basket modeling and the loading theory of the construction, and concludes, according to the results of the analysis, the hanging load can have a better stimulation of the stress situation of the hanging basket and it can save more costs in time, machines and personnel than some regular hanging basket load tests.
