| 摘 要： | 计算流体动力学方法可以解决复杂拱桥的三维绕流问题。以九堡大桥主桥为工程背景,通过数值模拟得出了大桥主梁的静力三分力系数以及空间拱肋的风荷载参数,最终分析得到该桥的风荷载响应及一类稳定安全系数,为复杂桥梁结构的抗风研究提供了参考。

| Abstract: | Computational fluid dynamics(CFD) can solve the problem of three-dimensional flow in complex arch bridge.Taking the Jiubao Bridge as the engineering background,three component coefficients of the girder and wind load parameters of the spatial arch ribs were obtained through numerical simulation.Finally,the response and buckling safety factor of wind load were analyzed.The result can provide a guide for the wind related research of complex bridge. |
