大型条状排列建筑群风压风洞试验研究

介绍了大型条状排列建筑群深圳金海湾花园外墙表面的脉动风压风洞试验结果，分析了该建筑物表面气流流动和风压分布的特点。分析表明，此类建筑群中各塔楼的风压分布相互干扰严重，风压分布具有整体性；沿长度方向迎风时。利于气流通过，正、负风压不大；沿宽度方向迎风时，迎风面积大，正、负风压较大，建筑物间形成的兜风效应和狭流效应使相关区域的风压更大。

Wind Tunnel Test Research on Large-Scale Strip-Like Building Group for Fluctuating Wind Pressure

The results of wind tunnel test on the wall s urfaces of strip-like building group, Shenzhen Golden Bay Garden, for the fluctu ating wind pressure are described in this paper. Based on these results the char acteristics of flow and wind pressure distribution are analyzed. The analysis sh ows that one building's pressure distribution is affected obviously by other bui ldings of this kind of building group, it's characteristics conform to whole gro up's shape. When the lengthwise group faces into the wind, the flow travels smoo thly, and the wind pressure on the buildings is lower. When the widthwise group faces into the wind, the windward area becomes large, flow shedding is stronger, and the wind pressure is comparatively higher. Pocket flow and narrow flow betw een buildings make the wind pressure value in some related area especially high.
