体育建筑风环境与空间形态耦合机理及优化设计研究

Wind break and wind guidance are the main contradictions of sports buildings form and microclimate optimization in cold regions, natural ventilation in the transition season is the breakthrough point for the low-carbon and health development. The research on the post-game sports buildings wind environment optimization and evaluation is almost of a theory blank under the national fitness strategic background.The safety and comfort of the loacal wind stagnation and strong wind, which are defined by the sports buildings form, are prominent and becomes its development bottleneck.So to excavate the interaction law between wind environment and sports building form is an important scientific problem. The project plans to explore sports buildings form coupling mechanism with wind environment by live testing,CFD simulation and wind tunnel test .The research contents are as follow: Establishes sports buildings wind environment database and evaluation Criteria by computer data technology by the live testing. Based on repeated modification of simulation collaborative design, clarifies wind environment distribution characteristics ,variation law and impact factors，reveals coupling mechanism between wind environment and sports building form. Based on wind simulation and wind tunnel test verification, constructs the sports building wind environment optimization method and sports building form optimization design strategies. It is important for the research to open the sports buildings form design and deepen hommization and greenization development from theoretical and practical perspectives.

防风、导风是寒地体育建筑形态与微气候优化的主要矛盾，过渡季节自然通风是其低碳健康化发展的突破口，而全民健身国家战略背景下非赛时工况的体育建筑风环境优化和评估研究几近理论空白。由建筑形态界定的风场局地滞风和局地强风等安全舒适问题日渐凸显并成为其发展瓶颈，因此厘清风环境与体育建筑形态之间的影响规律是亟待解决的重要科学问题。本项目通过现场实测、数值模拟和风洞试验方法，拟阐明体育建筑风环境与空间形态耦合优化机理，主要内容：通过典型形态现场实测调研建构寒地体育建筑风环境数据库和评估准则；依托模拟协同设计平台进行典型形态风环境模拟，表征不同工况下室内外风场分布特征、变化规律和影响因素，揭示体育建筑风环境与空间形态耦合机制；基于数值模拟和风洞试验参照验证，凝练体育建筑风环境优化方法和空间形态优化设计策略。预期成果将开拓体育建筑形态设计新理论，对推动体育建筑人性化、绿色化发展具有重要的科学意义和实践价值。
