| 摘 要： | 文章针对混凝土曲线箱梁桥转体施工预拱度的计算问题,结合一座支架现浇T型刚构桥梁,通过改变其计算模型中的平曲线半径、支架刚度、徐变模型,分析得到由恒载、预加力、收缩徐变及1/2静活载计算的预拱度的变化规律。

| Abstract: | In light of the camber calculation of curved concrete bridge constructed by rotation method,curve radius,rigidity of bracket and creep formula in the calculation model of a T type rigid frame bridge built on bracket were changed,and then law of bridge camber,that caused by constant load,prestressing force,shrinkage,creep and half of static live load appeared through analysis. |
