| 为了更加高效准确地评估地铁换乘站发生火灾事故的等级,文章基于火灾动力学模拟工具(FDS)模拟了宁波市某地铁换乘站的火灾现场,利用灰色系统理论改进了地铁换乘站火灾风险的评价指标体系,根据模糊分析法对地铁换乘站的火灾风险进行了评价,并且在模拟现场的基础上提出了相应的人员撤离方案。结果表明,该地铁换乘站的火灾风险综合评价为一般安全,影响疏散的各种因素导致各个出口的可用疏散时间只有4~7分钟左右。研究证明FDS能够很好地应用在地铁换乘站的火灾预防中,有利于火灾风险的评价与火灾来临时人员撤离方案的规划。本研究为特定环境范围中的火灾预防提供了重要参考。 |
| English Summary: |
| In order to estimate the grade of fire accident in subway transfer station more efficiently and accurately, based on the fire dynamics simulation (FDS), this paper simulates the fire scene of a subway transfer station in Ningbo, improves the fire risk evaluation index system of the subway transfer station by using the grey system theory, evaluates the fire risk of the subway transfer station according to the fuzzy analysis method, and puts forward the corresponding evacuation scheme on the basis of the simulation scene. The results show that the fire risk comprehensive evaluation of the subway transfer station is general safety, and the available evacuation time of each exit is only about 4-7 minutes due to various factors affecting evacuation. This study proves that FDS can be well applied in fire prevention of subway transfer stations, which is conducive to fire risk assessment and evacuation plan planning when fire comes. This study provides an important reference for fire prevention in a specific environment. |
