Results show that if the local deformation of individual segment is neglected in the determination of fabrication dimensions,errors in pre-assembled geometry will increase with the cantilever erection construction process,the quality and shrinkage of welding seam will be hard to control.
研究结果表明:若忽略梁段局部变形,则预拼线形的误差会随着悬臂拼装的进行不断放大,梁段顶、底板处的焊缝质量和焊接收缩变形将难以控制。
