摘要

为探讨建筑物发生火灾时火灾产品对人员疏散的影响ꎬ通过建筑物模型的全比例尺数值模拟提取火灾产品的相关参数ꎬ引入人员疏散速度系数的概念ꎬ,建立基于火灾产品影响的疏散速度模型。其次,ꎬ提出了一种确定安全疏散的新方法,并对考虑火灾产品影响的疏散进行了数值模拟。同时分析了喷淋强度和排烟量对速度系数的影响。结果表明,与传统研究方法相比,所建立的疏散模型能更好地反映火灾现场的疏散效果。增加喷淋和抽烟功能,可以有效降低火灾产物对疏散速度的影响。

Simulation study on personnel evacuation considering impacts of fire products
In order to explore impacts of fire products on personnel evacuation in the event of a fire in buildingsꎬ relevant parameters of fire products were extracted through full ̄scale numerical simulation of building modelꎬ concept of personnel evacuation speed coefficient was introducedꎬ and an evacuation speed model based on effects of fire products was established. Secondlyꎬ a new method to determine safe 第 6 期 叶成豪等: 考虑火灾产物影响条件下的人员疏散仿真研究 evacuation was put forward before numerical simulation was carried out for such evacuation considering impacts of fire products. Meanwhile influence of spray intensity and smoke exhaust rate on speed coefficient was analyzed. The results show that the proposed evacuation model can better reflect evacuation effects in the real fire site than traditional research methods. And addition of spraying and smoke extraction can effectively reduce impacts of fire products on evacuation speed.
