摘要:
为了探究风障挡风率和高度比对分离式双箱梁桥面行车风环境的影响,以某跨海通道中引桥分离式双箱梁为研究对象,开展了计算流体动力学(CFD)数值模拟研究。首先,建立了静态绕流数值模型并验证了网格密度无关性; 其次,采用数值模拟手段研究了风障对桥面风剖面的影响,分析了上下游车道位置风剖面及挡风高度随风障结构参数的变化规律,并与无风障的原断面进行了对比; 最后,通过桥面等效风速和侧风折减系数评估了风障挡风率和高度比对桥面行车安全的影响,同时结合断面三分力系数,引入风障综合评价指标,给出了风障挡风率和高度比的建议值。研究结果表明:不同挡风率和高度比的风障会使桥面车道风剖面产生明显变化,在来流上游距离风障越近的车道所受到的影响越显著; 增大风障挡风率和高度比可以提高减风效果,改善桥面行车风环境,但总体上导致阻力系数随之增大,即桥梁所受风荷载增大; 同时考虑风障减风效果和桥梁所受风荷载影响,保障分离式双箱梁上行驶的集装箱卡车和小轿车的行车安全,建议值取挡风率为75%和高度比为0.45。
Abstract:
To investigate the influences of wind barrier windproof ratio and height ratio on the bridge deck traffic wind environment of the twin-box girder, a twin-box girder of a viaduct in a sea-crossing channel was selected as the research object, and a computational fluid dynamics(CFD)numerical simulation study was conducted. Firstly, a static flow numerical model was established and the grid independence was verified. Secondly, the influence of wind barrier on the wind profile of the bridge deck was studied using the numerical simulation method. An analysis was conducted on the variation patterns of wind profiles at upstream and downstream lane positions and windproof height with changes in wind barrier structural parameters. A comparative analysis was conducted with the original cross section without wind barriers. Finally, the impacts of wind barrier windproof ratio and height ratio on driving safety on the bridge deck were assessed through the equivalent wind speed and crosswind reduction coefficient. Meanwhile, based on the three-component coefficients, a comprehensive evaluation index for wind barrier was introduced, and the recommended values for the wind barrier windproof ratio and height ratio were provided. The research results show that wind barriers with different windproof ratios and height ratios will significantly alter the wind profile of the bridge deck lanes, with the lanes closer to the wind barrier structure experiencing a more pronounced effect. The increases in the wind barrier windproof ratio and height ratio can enhance the wind reduction effect and improve the traffic wind environment for bridge deck. However, this also leads to an increase in the drag coefficient, resulting in higher wind loads on the bridge. Considering both the wind reduction effect of the wind barrier and the impact of wind load on the bridge, a 75% windproof ratio and a 0.45 height ratio are recommended to ensure the driving safety of container trucks and passenger cars on the twin-box girder.4 tabs, 17 figs, 32 refs.
