摘要
悬臂浇筑法充分利用了预应力混凝土承受负弯矩能力强的特点,将跨中正弯矩转移为支点负弯矩,提高了桥梁的跨越能力,在工程当中应用较多。结合工程实例对悬臂浇筑桥梁进行分析计算,有关经验可供相关专业人员参考。
The cast-in-place cantilever method is fully to utilize the characteristics of the pre-stressed concrete under negative bending moment capacity, to transfer the positive bending moment in the middle of span to the negative bending moment of pivot point, and to improve the spanning capacity of bridge beam,which is more used in the projects. According to the engineering cases, the article analyzes and computes the cast-in-place cantilever bridge. The relative experience can be referred for the similar projects.
