摘　　要：为研究设计初期主要形状参数,对大跨索膜挑篷结构风荷载的影响,采用计算流体动力学(Computational Fluid Dynamics,CFD)方法,对某挑篷结构初步方案的风荷载及流场进行了数值模拟。通过多类形状参数的比较,认为地形、挑篷倾角及看台的封闭性对结构风荷载及流场分布有较大影响,并给出建议设计参数进行风洞试验。In order to study form parameter at primary design period and its impact on wind load of large span membrane canopy structure, Computational Fluid Dynamics is used for study. Make numerical simulation for wind load and fluid flow of primary selection scheme of a certain canopy roof structure. Terrain, canopy roof dip angle and closure of bleachers will have influence on structure wind load and flow field distribution through comparison of multiclass form parameter. In addition, some design parameters are given for wind tunnel test.
