摘要:
为给火灾情景下管廊检修人员应急疏散和外部消防救援提供有益指导，采用火灾动力学软件对不同的通风系统（自然通风、机械负压通风和全面机械通风）与防火门、喷淋系统的不同开启状况等12种组合模式下的温度、能见度等参数变化进行分析，探究综合管廊火灾烟气优化控制模式。结果表明：进风系统、排烟系统、喷淋系统以及防火门合理的优化组合模式能够达到有效控制管廊火灾烟气的目的；火灾情景下，自然通风系统不能有效控制火灾烟气的发展，而机械负压通风和全面机械通风系统，如能及时启动喷淋以及关闭防火门，管廊内的烟气便可得到有效的控制。研究结果可为应急条件下人员疏散提供参考。
Abstract:
In order to provide useful guidance for the emergency evacuation of maintenance personnel and external fire rescue of utility tunnel under fire scenarios,the change of temperature,visibility and other parameters under 12 combination modes of different ventilation systems (natural ventilation,mechanical negative pressure ventilation and comprehensive mechanical ventilation) and different opening status of fire door and sprinkler system were analyzed by using the fire dynamics software,and the optimization control mode of smoke for the fire in utility tunnel was explored.The results showed that the reasonable optimized combination mode of the air intake system,smoke exhaust system,sprinkler system and fire door could achieve the purpose of effectively controlling the smoke in the fire of utility tunnel.Under the fire scenarios,the natural ventilation system could not effectively control the development of fire smoke,while the mechanical negative pressure ventilation system and the comprehensive mechanical ventilation system could effectively control the smoke in the utility tunnel if the sprinkler system could be started and the fire door could be closed in time.The results provide the reference for the personnel evacuation under the emergency conditions.
