摘要
通过对三峡工程永久船闸大型临时公路桥 2根大跨度全焊接钢箱形梁工厂焊接制作及现场组焊的实践 ,介绍了大跨度全焊接钢箱形梁的焊接工艺、组装顺序和焊接变形控制方法 。
Through the making and in_situ assembling the two all_welding large-span steel box beam which are designed for the temporary large-scale highway bridge on the shiplock of the Three Gorges project, the welding procedure, assembling sequence and welding distortion control method of the all-welding large-span steel box beam are described. And some useful experiences for reference in cases of the same kind are provided.
