| 摘 要： | 利用风洞试验方法,以上海陆家嘴金融贸易区建筑群及上海中心大厦为研究对象,讨论了不同粗糙度、不同风向条件下,高密度建筑群和超高建筑物对风环境的影响。结果表明:1)地表粗糙度越小,大风区范围越大。此外,建筑群的分布、排列形式会明显改变来流走向。2)超高建筑物由于其形态上下不一致,在一定条件下,不同高度处的风矢量存在明显差异。3)参照国外建筑物风环境舒适度评估标准,对模拟区域内行人高度处的舒适度进行了评估,并给出了3个风环境较差的区域。

| Abstract: | The wind tunnel experiments were carried out to study the impact of high-density building clusters and high-rise building on the wind environment,in case of different surface roughness and wind directions.The Shanghai Lujiazui Finance & Trade Zone and Shanghai Tower were selected as the test subject areas.The results show that the large wind area increases with the decrease of surface roughness,and the wind direction is easily affected by the building cluster distribution and arrangement.Under some conditions,the wind vector is varied at different height of high-rise building due to its inconsistent shape at upper and lower levels.According to a foreign wind environment comfort criteria on tall building,the average wind velocities at pedestrian level are evaluated,and three bad areas in aspect of wind environment are listed. |
