| 摘 要： | CFD(计算流体动力学)方法作为风洞试验的辅助手段,已越来越广泛地应用于桥梁断面选型及抗风设计分析中。采用CFD方法,对某轨道交通大跨度桥梁进行了二维流场数值模拟,得到流场的压力、速度和旋涡分布,还得到了不同高度主梁截面在-3°、0°、3°风攻角时的三分力系数,并对其随梁高的变化规律进行了分析。

| Abstract: | As an auxiliary means of wind tunnel test,CFD method is widely used in bridge deck section analysis and wind -resistant design.A large-span bridge of rail traffic is simulated in two-dimensional flow field to get the pressure,velocity and vortex distribution,and the tri-component coefficients of the main beam section when the wind angle of attack is in -3 ° ～ 3 ° at different heights,the variation laws of bridge beam at different heights are analyzed. |
