清江跨线双线特大桥桥墩模板受力分析

摘要

The paper has the detailed calculation on the stress of the bridge pier model of Qingjiang over-line and double-line super-large bridge along Yu-Li railway,including the plate,the shaft rib,the large transverse rib and the tension screw,undertakes the plate and transverse bar calculation of the side arc model,and illustrates according to the calculation result that the usage safety of the sizes of all components of the model can be guaranteed,the construction cost can be lowered maximally and its economic benefits is obvious.%对渝利铁路清江跨线双线特大桥桥墩模板受力做了详细检算,具体包括平面模板中的面板、竖肋、大横肋以及对拉螺杆计算,侧面圆弧模板中的面板、横向背筋计算。根据计算结果,模板各构件规格在选材时既保证使用安全,又能最大程度降低施工成本,经济效益可观。
