摘要
某大桥主桥钢箱梁板单元为正交异性结构,焊接制作过程中产生明显的角变形。本文结合实际工程中控制顶板单元焊接变形的方法,通过计算与有限元技术对关键问题进行了分析。
Steel box beam-slab belongs to the orthotropic structure,and obvious angle deformation may occur during the welding process.Based on the method to control the welding deformation of top slab applied in actual projects,some key issues are calculated and analyzed by using finite element technique.
