摘要
该文以某城市综合体为研究对象,在风洞中开展了大尺度建筑和密集建筑群对行人高度风环境影响的试验研究。基于阵风等效平均风速与项目区域的气候条件,给出了采用基于超越阈值概率的4种评价标准的评估结果。结果表明:对于坐,Force Technology-DMI标准最为严格;对于站,Isyumov and Davenport标准最为严格;对于行走,Michael J Soligo标准最为严格;针对不同的人类活动,UWO标准最为宽松。
Wind tunnel tests of pedestrian level wind environments influenced by large scale construction and dense buildings for a HOPSCA （Hotel, Office, Parking, Convention, Apartment） development were conducted. Estimations of the wind environment using four different criteria are presented and discussed based on the GEM and local climate information. The results indicate that Force Technology-DMI criterion is the most rigorous for sitting individuals, the Isyumov and Davenport criterion for standing individuals, and Michael J. Soligo criterion for walking individuals. Furthermore, the UWO criterion is the most undemanding for all human activities.
