摘　　要：为研究服装商店火灾蔓延和燃烧的特性及其对消防部队灭火作战的影响,按照真实的场景布置并进行了两次通风条件不同的服装商店火灾的实体灭火试验。试验结果显示由于服装商店内可燃物较多,燃烧耗氧量大,火灾的蔓延和强度受通风状况的影响较大。在供氧充足的情况下,服装商店火灾的蔓延发展可以分为引燃阶段、缓慢发展阶段和快速发展阶段三个阶段。当火灾发展到快速发展阶段的时候,火场的温度和烟气浓度很高,能见度低,灭火困难,导致灭火时间长,消防用水量大。In order to study the fire spread characteristics and the influence factors to fire fighting in clothing store fires, two full --scale fire suppression tests were performed under different ventilation conditions. The results of the tests show that due to the large amount of combustibles in clothing store, combustion needs a great deal of oxygen and the fire spread speed and fire size are greatly influenced by ventilation. At the condition of enough oxygen, the development of clothing store fire can be divided into three regimes： ignition, slow spread fire, fast spread fire. When the fire is in fast spread regime, the room temperature and the smoke density are very high, which make the fire fighting is difficult. Therefore, the fire extinguish time is prolonged and the needed fire fighting water is increased.
