[摘要] 奥林匹克公园网球中心为2008年北京奥运会网球比赛场所，其中10 000座中心赛场体型为花瓣型，12个结构单元（花瓣）间有较大开洞。开洞体型对风荷载非常敏感，迎风看台锥面的导风作用以及大开洞的穿透性，使得网球中心赛场的看台、罩棚的风压分布以及场内风环境明显不同于常规体育场。本文采用CFD方法对该结构进行了风荷载和风环境的数值模拟分析，风压系数与风洞试验吻合较好。

Abstract: Olympics Creen tennis centre will be the 2008 0lympic Games venue for tennis competition. The flower petal shaped center court, which is composed by 12 flower petal shape units, forms 12 holes between units. The special shape makes the arena sensitive to wind loads. The wind guidance function of the upwind cone - shape stand and the wind draft of the big holes make wind environment different from other common arenas. Computational Fluid Dynamics( CFD)  method is carried out to simulate wind loads acting on the special shape arena. Comparisons between the results from the present computation and the wind tunnel test were performed, which indicate that the precision of CFD technique is enough to predict the mean wind pressure distribution on this special building. As comparison the wind distribution of a closed shape arena is also considered.  Besides, the influence of different roof slopes and wind speed ratios are discussed to appraise the wind performance during tennis competition.
