Abstract Wind tunnel tests and CFD numerical simulations were coupled to study how the single and combined use of two aerodynamic measures—the inverted-L-shaped deflector and the upper central stabilizer—affects the vortex-induced vibration performance and flow field evolution of a vertical-web steel box girder. Results show that the effectiveness of combined measures differs from that of single ones, and multiple performance outcomes are possible for the combined ones. A proper height-to-width ratio for combination measures yields superior vibration suppression relative to single ones, whereas dimensional mismatch exacerbates torsional vortex-induced vibration. The varying effects of combined measures are caused by flow field differences resulting from variations in their dimensional proportions. In high-performance combinations, the vortex scale is suppressed by the inverted-L-shaped deflector through altered airflow separation, while the vortex evolution path is disrupted by the central stabilizer. Their coordinated action balances the fluctuating pressure difference between the upper and lower surfaces of the deck, significantly weakens vortex energy, and ultimately blocks vortex-induced resonance.

钝体钢箱梁气动措施组合的涡振控制效果
以直腹板钢箱梁为对象，选取倒L型导流板与上中央稳定板为典型措施，通过风洞试验与CFD数值模拟相结合的方法，分析单一措施与组合措施对涡振性能的影响差异及其流场演化机理. 结果表明：组合措施效果和单一措施效果具有差异性，组合措施效果存在多种可能性. 组合措施的适当高宽比例相比对应单一措施抑振性能更优，尺寸失配会导致扭转涡振恶化. 单一措施组合效果出现多种可能性的原因是组合措施的尺寸比例差异导致的流场差异. 在抑振效果优秀的组合措施中，倒L型导流板通过改变气流分离形态抑制旋涡规模，中央稳定板干扰旋涡演化路径，二者协同作用平衡断面上下表面脉动压力差，显著削弱涡振能量，阻断了涡激共振.
