摘　　要：绵竹市体育场的屋盖结构由悬挑钢屋面和落地飘带组成,结构形式较为复杂,使得屋盖表面风荷载分布和体育场风环境明显不同于常规的体育场。文章通过计算流体力学(CFD)对该结构进行了模拟,分析了该结构在不同风向角下的风压系数分布,讨论了屋盖开缝与否对风场的影响,并对体育场行人高度处的风环境进行了模拟评估。The roof of the Mianzhu Stadium is composed of the cantilevered steel cover and the ribbon-like structure connecting to the floor.This special shape makes the wind loads and the wind environment complex.The computational fluid dynamics（CFD） method was adopted to simulate wind loads acting on the stadium in different wind directions.The influence of the joint gap between the roof and stand was considered in the simulation.The pedestrian wind environment around the stadium was also assessed in this paper.
