摘　　要：与商业、住宅建筑相比,现阶段针对大学校园的风环境研究较少。考虑到气候环境的变换,现应用"五日滑动平均值"方法,确定了该校园风环境的主要参数,并运用CFD模拟分析的方法,对宿舍区室外风环境进行定量分析和设计优化。模拟得出结论如下:宿舍区在自然通风条件下,内部风环境相对稳定,不会对行人造成明显干扰,同时有利于空气流动;由于建筑物的整体朝向,导致外围建筑迎风面与背风面的风压明显,易造成冬季冷风渗透;外围建筑易因"拐角效应"形成连片的拐角风等。由此提出在宿舍区的西北与西南方向之间密植绿化带、栽种常绿植被代替冬季落叶乔木、增加建筑立面粗糙度等优化措施来改善宿舍区的内部环境,并进行相关的模拟验证,结果表明,提出的措施对宿舍区风环境有较大的改善。Compared with commercial and residential buildings,there are few studies on the wind environment of university campus at this stage.Considering the change of climate and environment,this paper uses data statistics and applies the“five-day sliding mean value”method to determine the main parameters of the wind environment in this campus,and with the aid of CFD simulation analysis,the quantitative analysis and optimization of outdoor wind field are carried out.The simulation results are as follows:in the condition of natural ventilation,the dormitory area is relatively stable in the internal wind environment,and it will not cause obvious interference to the pedestrians,and it is beneficial to the air flow.Because of the overall orientation of the buildings,the wind pressure of the windward and leeward surfaces of the peripheral buildings is obvious,and it is easy to make the winter cold wind permeate;the peripheral buildings are easy to form the corner wind of the“corner effect”.Therefore,the green planting zone between the northwest and the southwest of the dormitory is proposed;the planting of the green plant is replaced by the winter deciduous tree;the optimization measures of increasing the roughness of the building elevation to improve the internal environment of the dormitory and the related simulation verification have been carried out to prove that the proposed measures have a great improvement on the wind environment in the lodging area.
