Novel split box girder structure capable of inhibiting vortex vibration

The invention relates to a novel split box girder structure capable of inhibiting vortex vibration, which comprises two or three box girders which are horizontally arranged, and tuyeres are arranged on the outer sides of the box girders on the two sides; a groove is formed between every two adjacent box girders, webs on the adjacent sides of every two adjacent box girders are wavy webs, the wavy webs are of wavy structures arranged in the length direction of the bridge, and the waves are periodic sine waves arranged in the length direction of the bridge or periodically-changing waves arranged in the length direction of the bridge. While the excellent flutter performance of the section of the split box girder is ensured, the vortex vibration performance of the bridge is safely, reliably, economically and reasonably improved. 本发明涉及一种可抑制涡振的新型分体箱梁结构，包括水平设置的两个或三个箱梁，位于两侧的箱梁的外侧设置有风嘴；相邻的两个箱梁之间设置有开槽，两个相邻箱梁的相邻一侧的腹板为波浪形腹板，所述波浪形腹板的形状为沿桥长方向设置的波浪形结构，所述波浪形为沿桥长方向设置的周期性的正弦波形或沿桥长方向设置的周期性变化的波形。本发明在保证分体式箱梁断面优良的颤振性能的同时，安全可靠、经济合理地
