基于建筑楼梯与走道疏散宽度的匹配度,通过理论计算方法研究建筑中人员疏散的人流流量、密度、股数与疏散宽度的关系,首次提出冗余宽度系数,利用国外疏散理论和研究数据论证冗余宽度系数的合理性,并通过工程实例分析确定其可行性,为消防设计和审核提供多角度思考。 Based on the matching degree between the evacuation width of the stairs and the walkway, the relationship between evacuation flow, density, stock number and evacuation width was studied by theoretical calculation method. The redundant width coefficient was proposed for the first time. Based on the evacuation theory and the research data, I width coefficient of reasonableness, and through the analysis of engineering examples to determine its feasibility for the design and review of fire protection to provide multi-angle thinking.
