摘要为研究外置纵向排水管对扁平箱梁涡振性能的影响，以某大跨度扁平钢箱梁悬索桥为工程背景，采用1:50节段模型风洞试验，分别对有无外置纵向排水管的扁平箱梁涡振性能进行研究。试验结果表明：原设计扁平箱梁在0°与±3°风攻角下均发生显著涡激振动，通过在检修车轨道处设置内侧导流以及将外侧防撞栏杆隔二封一可以有效抑制断面涡振振幅至规范限值以下，但沿桥纵向设置外置排水管会显著降低主梁涡振性能，并使原有效涡振制振措施失效。通过CFD对主梁断面二维流场的模拟结果表明，外置纵向排水管会同时改变扁平箱梁断面下表面迎风侧与背风侧斜腹板处的旋涡脱落形态，在此基础上，通过在外置纵向排水管处增设导流板与水平稳定板用以改善该处的气体绕流形态，并据此提出了一种水平稳定板、导流板与间隔封闭栏杆共同作用的组合气动措施。试验结果表明，该组合措施能够显著抑制主梁的涡激振动，同时数值模拟结果表明，能够显著减弱斜腹板处的旋涡脱落现象，从而降低主梁受到的周期性涡激力，是该组合气动措施能够抑制梁体涡激振动的主要原因。

Abstract：In order to investigate the influence of the external drainage pipe along the bridge on the vortex-induced vibration (VIV) of the flat steel box girder, a long-span suspension bridge with flat steel-box girder was taken as an engineering example. The VIV performance of the girder with or without the drainage pipe was studied by using 1:50 scale section model wind tunnel test. The tests show that significant VIV occurs in the original box girder at both 0° and ±3° wind attack angles. The VIV amplitude of the section can be effectively suppressed below the standard limit by setting the inner baffle at the track of the maintenance vehicle and change the railing ventilation rate. However, setting the drainage pipe along the longitudinal direction of the bridge will significantly reduce the VIV performance of the girder and make the original effective aerodynamic countermeasures ineffective. The two-dimensional flow field around the cross section of the girder was modeled by CFD. The calculation results show that the installation of a longitudinal drainage pipe will simultaneously change the vortex shedding pattern at the windward and leeward inclined web of the lower surface of the flat box girder section. On this basis, by adding baffles and the horizontal stabilizer at the drainage pipe, a combined aerodynamic measure formed by the combination of the horizontal stabilizer, the baffle and closed barriers is proposed. The test results show that this measure can effectively suppress VIV of the girder, and the VIV suppression mechanism of the combined aerodynamic measure is studied by using computational fluid dynamics. The calculation results show that the measure can significantly reduce the cross-sectional vortex shedding size, and significantly reduce the periodic aerodynamic force on the girder, thereby suppressing the VIV of the girder.
