Abstract: The pedestrian wind environment around a commercial center in Beijing was investigated in the wind tunnel. The pedestrian level wind velocity distributing could be attained by analyzing the result of test points arranged around the models. Based on the pedestrian level wind comfort criteria, which categorized different ranges of wind velocity as being appropriate for certain types of pedestrian activities and gave the corresponding acceptable frequencies of occurrence, the pedestrian wind environment was assessed quantitatively combined with the local wind climate statistic records. Some useful guide was provided to improve the comfortability in the potential uncomfortable or dangerous locations.

Key words: pedestrian wind environment, wind tunnel, pedestrian level wind comfort criteria

摘要: 采用风洞试验方法, 对北京某商业中心行人风环境进行研究, 通过对行人活动区域测点风速的统计分析, 得到该区域16 个风向角下的行人高度风速分布。结合气象资料, 利用针对不同行人活动类型的大概率发生事件的行人风环境评估标准, 对该商业中心的风环境品质进行定量评估, 并对可能造成行人不舒适或危险的区域提出改善建议。
