| 摘 要： | 介绍中国国家大剧院模型表面风荷载的风洞实验结果。首先对它的半椭球表面在大气边界层中的风压分布及增加表面粗糙度的影响进行研究，实验结果表明在不同风向下它的风荷载具有很好的规律性。有环境影响的对比实验结果表明人民大会堂对大剧院的风荷载有较大的影响。

| Abstract: | The main results of the wind tunnel experiment on the 1/200 model of the Chinese National Grand Theatre were introduced.At first,the wind pressure distributions of its semi ellipsoidal surface in an atmospheric boundary layer flow were simulated,and the effect of the surface roughness was researched.The results indicated a reasonable regularity of its wind loading in various wind directions.On the problem of the environmental influence,it demonstrated that there existed a great effect for the pressure distribution of the Great Theatre when the Grand Hall is at east. |
