| 摘 要： | 本文介绍了深圳机场航站楼扩建工程外墙表面及屋面风压的风洞试验结果，分析了该楼屋面风压的分布规律及几个重要的影响因素。试验结果表明：大型屋面风荷载主要集中在屋面悬挑部分，尤其是前缘处；前缘处的负压最大且变化剧烈，其值与悬挑长度、悬挑部分水平倾角、前缘外形等有关。

| Abstract: | In this paper, the wind tunnel test for pressures acting on wall surfaces and roof of the Ex-tention Project of Shenzhen Airport Building was introduced. The distribution regularity of the roof pressure and a few important influential factors were analyzed. The test results showed that the wind loads acting on the large roof structure were mainly concentrated in the cantilever part, expecially on its edge. The suction on the edge was the biggest but changed drastically, and the pressures are closely related to the cantilever length, the horizontal angle of the cantilever part and the edge shape. |
