某批零兼营商场疏散人数换算系数分析

Research on conversion coefficient of evacuation crowds in wholesale and retail markets

根据批零兼营商场存货量大、火灾荷载大、人员流动量大以及建筑体量大的特点,对某服饰商城工作日和黄金周的客流量进行实地调查,采用正态总体均值与方差的区间估计原理,计算该市场疏散人数换算系数,并与各标准规范和文献中各类商业建筑的实地调查数据进行对比分析,提出此类商业建筑疏散人数换算系数的参考值,建议未来建筑防火规范修订中疏散人数换算系数取值可根据商业所在城市、商业经营方式、范围等因素细化分类。

Based on the large amount of inventory, big fire load, large crowds and big building volume of the wholesale and retail market, the paper invested the customer traffic of a cloth store on weekdays and in golden week. It used normal population mean and variance of interval estimation principle, drew the conversion coefficient of the number of evacuees. Comparing the results with the data from codes and literatures of various types of commercial buiidings, the paper proposed the reference conversion coefficient of similar commercial building, It sugges- ted that the conversion coefficient of the number of the evacu- ees, in the revision of the code for fire protection of building, can be classified according to the different factors in future, such as the kinds of cities, the types of business, the scope of commercial building and so on.
