某城市广场室内步行街消防设计探讨

摘要

针对某室内步行街的建筑特点,分析其防火设计存在的问题,如防火分区、安全疏散等.提出相应的解决方法,如将步行街作为“临时安全区”,按一个防火分区设计,并采取一系列措施限制步行街内的火灾烟气蔓延及保证人员疏散的安全等.应用消防性能化设计的方法加以评估,分析其火灾危险性,用计算机模拟程序计算设定火灾场景下的火灾烟气、温度等火灾动力学参数,计算人员疏散情况.%Against the building feature of an indoor pedestrian street, problems during the fire safety design, such as fire district and safety evacuation, were analyzed. Solutions were put forward, such as taking the pedestrian street as a temporary security zone and a fire district, and taking a series of measures to control the smoke and ensure the safety evacuation. Performance-based fire safety design was utilized, firstly the fire hazard was analyzed, secondly the smoke and temperature in specified fire scenes were simulated, and then the evacuation was calculated.
