摘要 以实现商业综合体室内步行街"准安全区"为目标,对自然排烟和机械排烟两种烟气控制措施的有效性进行数值模拟研究。采用FDS和Building-Exodus模拟方法,在两种烟气控制措施下分别计算商业综合体室内步行街内的危险临界值TASET和人员安全疏散需要时间TRSET。研究结果表明:适当的烟气控制措施是"准安全区"实现的充分条件,在同等条件下,自然排烟的有效性优于机械排烟。计算结果表明,自然排烟面积与排烟效果成正比。研究证明,若将自然排烟和机械排烟相结合,可以有效应对火灾时多种不利情况,增强排烟的可靠性。 In order to achieve requirements of "quasi-security zone" in a commercial complex indoor pedestrian street,this paper simulates the effectiveness of numerical simulation of two kinds of natural ventilation and mechanical exhaust gas control measures.FDS and Building-Exodus simulation methods are used to calculate the risk of indoor pedestrian threshold TASET and the safety of evacuation time TRSET under the condition of smoke control measures in the two commercial complexes.The results show that: the appropriate smoke control measures are prerequisites for "quasi-security zone" and under the same conditions,the effectiveness of natural smoke is better than mechanical exhaust.The results show that natural ventilation and smoke effect is proportional to the building area.Studies have shown that the combination of the natural and mechanical smoke exhaust can effectively respond to a variety of fire conditions,enhancing the reliability of smoke ventilation
