摘　　要：本文结合 1座将建于强风区的大型体育场的实际建设情况 ,在风洞中对该体育场的 1、2期工程分别进行了试验 ,仔细分析了其主看台悬挑屋盖上的风压分布 ,并对干扰影响进行了讨论 。A wind tunnel test of a stadium model has been carried out in two phases according to the actual construction situation to investigate the wind pressure distributions on the grandstand cantilevered canopy roof of the stadium.The interference effects were discussed.Some conclusions about the wind pressure characteristics from the analysis and the discussion might be used as reference for the analysis of wind induced vibration responses of the structures of these kinds.
