中文摘要: 作为大量人群瞬时高密度聚集的公共活动场所,保障使用者安全疏散是大型体育场馆建筑设计中一个极为重要的问题。由于大型体育场馆空间规模的超大性、功能流线的多样性、人员疏散的复杂性特征,使得此类建筑的安全疏散设计无法实现应有的准确性与高效性,难以与整个设计过程动态化结合,缺乏有效的方法指引,成为制约大型场馆建筑安全疏散效果和设计水平的瓶颈问题。 本课题采用虚拟人群仿真技术手段,进行大型体育场馆安全疏散设计方法研究。揭示使用人群疏散过程与建筑环境互动规律,建构安全疏散路径模型并通过虚拟人群仿真方法分析测试,将研究结果转化为参数方程;在此基础上应用参数化技术建立安全疏散动态模型,研究其运作流程及安全疏散设计策略,进而提出基于虚拟人群仿真技术的大型体育场馆建筑安全疏散设计方法,并结合具体工程案例开展实证研究,为大型体育场馆安全疏散设计提供科学的、可操作性强的辅助工具和设计方法。

英文摘要: As public spaces for large and high-density crowd gathering, keeping users safe evacuation is a pre-eminent issue for the architectural design of large sports venues. Because of large sports venues are featured by large spatial scale, diverse function and circulation, and complicated evacuation, the safe evacuation design of this type of buildings could hardly achieve expected accuracy and high efficiency, in dynamic combination with the designing process, and lack of effective instructions and methods, which become the bottleneck problem constraints safe evacuation effectiveness and design level of large sports venues. This study uses virtual crowd simulation techniques to carry on the safe evacuation design method research of large sports venues. It reveals the interaction of the evacuation process of user crowd and the built environments, constructs safe evacuation route model and analyzes the performance by virtual crowd simulation technologies, converts the results to parametric equations; and further uses parametric techniques build dynamic model for safe evacuation, studies its operation procedure and safe evacuation design strategies, then bring forward safe evacuation design method for large sports venues based on virtual crowd simulation technologies, and conducts empirical study by practical projects
