摘要
随着《中国足球改革总体方案》《中国足球中长期发展规划(2016—2050年)》的相继出台和足球产业化的内需驱动,专业足球场的发展涌动渐露端倪。由球场罩棚等界定的内场风环境的优劣是影响球员技战术水平临场发挥和比赛结果的重要因素,而我国相当大的国土区域处于大风地区,因此,如何利用建筑设计手段营构出利于足球比赛的内场风环境成为体育建筑界亟待解决的重要科学问题。首先以30 000座左右的中型专业足球场为实验对象。进而以STAR-CCM+9.04.009作为模拟平台,5 m/s、10 m/s、15 m/s三种不同风速作为初始条件进行数值模拟。然后基于风场分布均匀性、风速变化稳定性以及针对大风地区的降低风速等准则对内场风环境进行评价分析,尝试揭示不同罩棚形态对足球场内场风环境的影响机制。进而提出风环境响应的专业足球场罩棚形式设计策略以供参考。
After the issue of General Plan of Chinese Football Reform and Mid Term Development Plan of Chinese Football(2016-2050), the development of professional football field is beginning to show up. Field wind environment will make serious impact on players’ performance and game result,while canopy form plays great effect on field wind environment, vast territory in China is in the windy area, So how to make use of architectural design means to create a favorable environment for the wind of football has become an important scientific problem to be urgently solved in sports building. Firstly, around 30 000 medium-sized football fields are taken as subjects,then STAR-CCM+ 9.04.009 is used as the simulation platform, 5 m/s, 10 m/s and 15 m/s are performed as initial conditions to simulation. After that, based on the distribution uniformity of wind field, the stability of wind speed change, and wind speed reduction principle for the strong wind area, the field wind environment is evaluated and analyzed, which is to reveal the different canopy morphology on the football field infield wind environment influence mechanism. Finally form wind environment responsive design strategies of professional football stadium were put forward for reference.
