风环境响应的寒地专业足球场界面形态多目标优化设计

Multi-Objective Optimisation Design of Professional Football Stadium Interface Forms in Cold Regions Based on Wind Environment Response

寒冷地区冷热赛季气候变化迥异,专业足球场风环境对球员竞技水平及观众观赛舒适度均有重要影响。本文通过寒地典型城市天津的现场实测建构专业足球场风环境评估准则,基于CFD模拟实验,挖掘出球场风环境与界面形态的耦合影响机制,提出风环境响应的专业足球场多目标优化设计策略。研究表明,有顶侧间隙、侧界面南北侧布置为实体的上倾罩棚足球场在天津地区风环境性能最优。

The climate changes differ between the cold and hot seasons in cold regions. The wind environment in professional football stadiums has an important influence on the athletic level of players and the comfort level of spectators. In this paper, the evaluation criteria for the wind environment of professional football stadiums are constructed by field measurements in Tianjin, a typical city in cold regions. Based on CFD simulation experiments, the coupling influence mechanism between wind environment and interface form is excavated,and multi-objective optimisation design strategies for the wind environment response of professional football stadiums are proposed. The research shows that football stadiums with upward canopy, top-side gap and solid interface on the north and south sides have the best performance in the wind environment in Tianjin..
