不同城市服装店火灾荷载调查和置信度分析

摘要

Through the fire load survey of clothing shops in five representative regional cities of China, the basic fire load data and distribution law have been obtained. The results showed that the average fire load densities of clothing shops in Shanghai and Shenzhen are lager, followed by Chengdu, Shenyang and Xi an. The average fire load density is 566. 6 MJ/m2. The maximum and minimum values are 2 490 MJ/m2 and 140 MJ/m2. Also the fire load survey results can achieve more than 90% confidence.%通过对国内5大区域代表性城市服装店火灾荷载的实地调查,统计分析了服装店的火灾荷载基础数据和火灾荷载密度的基本分布规律.结果表明,深圳和上海平均火灾荷载密度较大,其余依次为成都、沈阳和西安；火灾荷载密度平均值为566.6 MJ/m2,最大为2 490 MJ/m2,最小为140 MJ/m2,且火灾荷载调查结果能够达到90％置信度以上.
