摘要:

城市综合管廊是城市的生命线工程,一旦发生电缆火灾,不仅会造成管廊结构的破坏,还会影响城市的正常运转。运用CFD模拟技术建立综合管廊模型,对综合管廊内电缆火灾发展过程进行数值模拟,通过分析防火分区间距对电缆火灾的影响,得到不同工况下的管廊内热释放速率、管廊内温度分布、管廊内烟气扩散及一氧化碳浓度分布等情况。所得结论可为城市综合管廊设计及消防决策提供依据。

Abstract:

Urban utility tunnels are the lifeline engineering of a city. A cable fire inside the utility tunnel will not only cause damage to the structure,but also adversely affect the normal operation of the city. A finite element model of the utility tunnel has been established by CFD to simulate the process of cable fire in the utility tunnel in order to collect the heat release rate,the safe evacuation time of the serviceman,maximum temperature distribution,smoke diffusion,carbon monoxide concentration distribution in the utility tunnel,and analyze the influence of fire compartment distance on cable fire. The conclusions of the simulation can provide the basis for the design of urban utility tunnel and fire protection decision-making.
