地铁车辆段运用库防火设计的探讨

Discussion on Fire Protection Design of Rail Transit Vehicle Depot

为确保地铁车辆运用库防火安全,本文根据地铁车辆段运用库的工艺需要和建筑几何特征,提出防火设计难点,从消防车道、防火分隔、安全疏散以及消防设施等方面提出防火设计方案,利用消防安全工程学原理,设定典型火灾场景,通过数值模拟计算进行验证分析。结果表明:防火设计方案能够满足有效控制烟气蔓延和人员安全疏散的设计目标。

In order to ensure the fire safety of the rail transit vehicle depot,according to the technical needs and architectural geometrical characteristics of the rail transit vehicle depot,this paper analyzes the difficulties of fire prevention design,and puts forward the fire prevention design solution from the fire lane,fire separation,safety evacuation and fire prevention facilities.Based on the principles of fire safety engineering,typical fire scenarios are set up and verified by numerical simulation.The results show that the fire prevention design solution can meet the design objectives of effectively controlling the spread of smoke and safe evacuation.
