摘　　要：对“三合一”场所建筑特点和火灾形势进行总结,利用PyroSim软件建立典型火灾场景模型,研究火灾发生发展规律。通过设置不同喷头工作压力和不同喷头布置间距等工况进行数值模拟,对比分析不同工况下火灾发展态势和控火效果,探讨该类场所简易自动喷水灭火系统的设置方案。结果表明:在“三合一”场所应用简易自动喷水灭火系统是有效的,考虑自动喷水灭火系统安装成本及水源供水实际,选择喷头工作压力为0.05 MPa、布置间距为4 m的设置方案较为理想。On the basis of the building characteristics and fire cases of“three-in-one”places,a typical fire scenario model is established by PyroSim software to study the law of fire occurrence and development.By setting different working pressure and different spacing of the sprinklers,the fire development trend and fire control effect under different conditions were simulated to compare and analyze the fire development and fire control effect under different working conditions,and find out the setting of easy-to-install automatic sprinkler system in such places.The results show that the installment of an automatic sprinkler system is effective in the“three-in-one”places.Considering the installation cost of automatic sprinkler system and the actual water supply,it is ideal to set the sprinklers with a working pressure of 0.05 MPa and a layout spacing of 4 m.
