| 摘 要： | 下承式钢管拱系杆拱桥在拱肋安装、钢管混凝土浇筑、横梁安装和现浇横梁、桥面板湿接头时对拱脚产生的水平推力极易造成桥墩位移,通过对不同过程中的水平力计算,确定体外束张拉方案,使水平力通过体外束得以平衡。

| Abstract: | Horizontal push will arise Pier displacement of the through arch bridge of concrete-filled steel tubes under the condition of erection of arch ribs, concreting process, transverse beam pouring and installation. With the horizontal push calculation of different course, the tension design of externally cables will be determined, and the horizontal force is balanced. |
