Analysis on Layouts of Pedestal and Adjacent Podiums in Hangzhou in Wind Environment

  • 摘要: 为探究高层办公建筑基座式与毗邻式裙房布局对室外场地行人高度(1.5 m)处风环境的影响,选择地块内单幢高层建筑为研究对象,从裙房的位置、高度、迎风面宽度和进深状况对基座式与毗邻式裙房布局进行讨论,利用穷举法得到多种典型布局,并通过CFD (computational fluid dynamics)流体力学模拟软件Phoenics对地块内的建筑室外风环境进行模拟,对比得到基座式与毗邻式裙房的最优布局模式. 研究结果表明:在杭州高层建筑密集地块进行高层办公建筑裙房设计时,毗邻式裙房布局优于基座式,当裙房高度设计范围在15.0~20.0 m,裙房迎风面宽度设计范围为70.0 m左右,裙房迎风面进深长度在50.0~60.0 m时,风环境状况最好.
