摘要:
为研究桥面水马布置对桥梁涡激振动的影响,以某大跨度悬索桥为工程背景,基于计算流体力学(CFD)方法,研究不同风速、桥面水马布置方案下的桥梁断面受力情况及其周围流场的变化规律。结果表明:在桥面上布置水马能够改变桥梁断面周围流场的压力和速度分布,在桥梁上部和背风侧产生漩涡,可观察到明显的漩涡脱落现象,与无布置水马的桥梁相比,其发生涡激振动的可能性大大提升;水马与桥面边缘的距离越大,漩涡脱落现象越不明显,桥梁发生涡激振动的可能性越低。
Abstract:
In order to study the influence of bridge deck barriers arrangement on bridge vortex-induced vibration, taking a long-span suspension bridge as the engineering background, based on the computational fluid dynamics(CFD)method, the stress situation of bridge section and the variation of surrounding flow field are studied under different wind speeds and bridge deck barriers arrangement. The results show that the arrangement of the barriers on the bridge deck can change the pressure and speed distribution of surrounding flow field of bridge section, and the vortex is generated in the upper part and the leeward side of the bridge, obvious vortex shedding phenomenon can be observed, and compared with the bridge without the barriers, the possibility of vortex-induced vibration increases greatly. The greater the distance between the barriers and the edge of the bridge deck, the less obvious the vortex shedding phenomenon, and the lower the possibility of vortex-induced vibration of the bridge.
