地铁火灾人员逃生的模拟与分析

本文针对地铁火灾人员逃生这一问题，系统分析了地铁火灾与人员逃生过程与特点，在此基础上，提出了地铁火灾人员疏散时间计算模型。通过实验与软件，对地铁火灾的烟气的温度与扩散进行模拟，确定了地铁火灾人员疏散可用时间，总结了人员疏散所需时间的计算方法。结合了上海某地铁站的实例进行安全性分析，使得本文所提出地铁火灾疏散时间模型得以运用。

Simulation and Analysis of Safe Evacuation in Subway Fire

To solve the problem of safe evacuation from a subway station under fire, this paper systematically analyzes the characteristics and the process of the fire and the evacuation, establishes a computational model for people evacuation time. Through the numerical simulation of temperature change and smoke distribution with practical experiment and related software, the available time of safe evacuation is determined as well as the calculating method. Moreover, the theory is proven to be effective by an application in a safety assessment case of a subway station in Shanghai.
