摘要
针对一些采用节段悬臂施工桥梁使用期间挠度过大的问题,分析阐述了竖向接缝对桥梁竣工后期挠度的影响,通过对竖向接缝问题三种构造处理方案的分析比较,得出中小桥型建议用竖直接缝,大桥以及超大桥建议采用斜接缝的结论。
Aiming at the problems of the too large flexibility of arm construction bridge in utility, it analyses and represents the affection of vertical cracks to the flexibility in the later phase of completion of bridge. Through analyzing and comparing the three structure management program of the problems of vertical cracks, it deduces that it is advised to use the vertical cracks of medium and small bridges and it is apt to use the oblique cracks of large and super large bridges.
