大型商场建筑营业厅疏散人数的调查研究

Research of evacuation crowd in the business hall of large department stores

以大型商场建筑营业厅疏散人数的确定为研究目标 ,选择西安民生百货大厦为研究对象 ,分别以正常工作日、双休日及长假黄金周为调研时间。通过现场人流实测、统计验证分析 ,以双休日人数为基础 ,以黄金周人数为上限 ,求出了大型商场建筑营业厅疏散人数换算系数区间。并与《商店建筑设计规范》JGJ4 8- 88规定的换算系数做了比较研究 。

Focuses on the deternination of the evacuation crowd in business halls of large department stores.Xi'an Minsheng Department Store,a large department store in the capital city of Shaanxi Province of China,has been selected as the case building to conduct the investigation.The investigations have been conducted on weekdays,weekends and also holidays.Based on the experiments and statistical analysis on the evacuation crowd in business halls of the department store,this paper has given the interval estimation for conversion coefficient of the evacuation vrowd in the business hall of large department stores,in which the evacuation crowd on weekends as the base and the evacuation crowd on holidays as the upper limit.Comparison with the proposed conversion coefficient and the conversion coefficient prescribed by the Code for fire protection design of store building (JGJ48-88)shows the reasonability of the application of the interval estimation for conversion coefficient in the perfrmance-based fire protection design.
