摘要:
由于现在城市建筑呈现高层化和密集化的趋势，高层建筑对其所处地块内的风环境的影响十分显著，并且进一步影响到其室外行人的舒适性．改善高层建筑周边风环境是一个亟待解决的问题．首先，通过对杭州市钱江新城四季路地块6栋高层建筑群的周边风环境进行实测，筛选出建筑群体朝向对室外风环境影响较大的部位并确定测点．其次，针对所发现的风环境不佳问题，通过建立地块模型，不断改变各建筑单体的朝向角度，得到8种典型朝向布局．最后，利用CFD流体力学数值分析模拟软件phoenics对8种布局进行模拟，得到人行高度(1.5 m)上的风速比的分布情况．对比发现，通过建筑朝向的改变能够达到优化高层建筑群周围风环境的目的，通过探求风环境与建筑朝向之间的关系，研究结果为本地区进行高层建筑群体朝向设计时提供参考．
Abstract:
Due to the trend of high-rise and densification of urban buildings, high-rise buildings have a significant impact on the wind environment in their plots, and further affect the comfort of outdoor pedestrians to improve the wind environment around high-rise buildings, which is an urgent problem to be solved. First of all, in this paper, six high-rise buildings in Qianjiang New Town, Hangzhou City, were measured and the location of the building group towards the outdoor wind environment was selected and the points were determined. Then, by constantly changing the orientation of the building blocks, eight typical layouts were obtained. Finally, the CFD fluid dynamics simulation software phoenics was used to analyze the distribution of the wind speed ratio at the height (1.5 m).It is found that the change of the building orientation can achieve the optimization of the surrounding wind environment of the high-rise buildings. This paper, by exploring the relationship between wind environment and building orientation, provides a reference for the design of high-rise building groups in the region.
