摘要 城市中高大建筑物和建筑群会显著改变城市近地面层风场结构.在有较强来流时,建筑物周围某些地区会出现强风;如果这些强风区出现在建筑物入口、通道、露台等行人频繁活动的区域,则可能使行人感到不舒适、甚至产生伤害,产生行人风环境问题.因此在设计阶段,应对建筑物的风环境做出评价,以对可能出现的行人风场问题,提出改进措施.采用风洞热线测量、风洞刷蚀技术和计算流体力学数值模拟等方法,对北京地区某高大建筑在北京地区盛行风条件下的风环境,开展物理模拟和数值模拟,并进行相互验证和比较.研究结果表明,3种方法得出行人风场结构和分布基本一致.研究还分析了各方法的长处和局限,指出3种方法的相互配合,可使城市高大建筑的行人风环境研究更为科学、合理.
