摘要
为了缩短施工周期,节省钢材用量,通过方案比选,泉州湾跨海大桥主塔上横梁支架采用了一种牛腿支架法进行施工。通过对支架结构进行分析计算表明,该牛腿支架结构满足设计及规范要求;施工中采用该牛腿支架结构成功完成了上横梁浇筑,验证了其安全可行性。
To shorten the construction period and save steel products consumption,a bracket structure which is supported by corbels is adopted for the constructionon of the Quanzhou Bay Bridge's top crossbeam according to the comparison of construction scheme,the analysis on the bracket structure is made,the calculation shows that the bracket structure meets the need of specification and construction,and the successful implementation of the bracket structure indicates that the bracket structure is safe and feasible.
