摘要
对不同拱轴线形的下承式钢箱系杆拱桥进行数值模拟分析,得出拱肋内力分布于拱轴线形变化的规律,并通过比较确定合理的拱轴线形,可作钢箱系杆拱桥设计拱轴线形时的参考。
The numerical simulation analysis is carried out for the different arch axis alignments of through steel box bowstring arch bridge. The rule of arch rib inner force distributed in the change of arch axis alignments is given. The comparison and determination of reasonable arch axis alignments can be referred for the design of arch axis alignments of steel box bowstring arch bridge.
