摘要
目前大跨度钢箱梁悬索桥在国内桥梁建造中运用广泛,以重庆某长江大桥为研究对象,通过加设横向制造预拱、加放节段余量及焊接收缩量、采用横隔板单元二次切割、锚箱块体制作安装等工艺方法,对大跨度钢箱梁悬索桥加工制造精度控制进行研究。
For the time being, wide-span steel box beam suspenmon bridge is comprehensively useu in domestic bridge construction project. Based on a bridge project crossing over the Yangtze river, this paper analyzed various methods for processing accuracy control of wide-span steel box beam suspension bridge, including transverse pre-arching, adding section allowance and welding shrinkage, transverse diaphragm unit secondary cutting and anchor cell fabrication and installation, etc.
