摘要
为尽快发现和控制火灾,使古建筑的消防投资更经济有效,需进行试验研究。但古建筑不能进行现场试验,通过基于火灾动力学的场模拟软件FDS5.0,以山西圣母殿为例,建立物理模型,模拟火灾发生、发展过程,得出火灾烟气蔓延过程中浓度和温度随时间变化的不同分布。通过对模拟结果分析,对圣母殿中感烟和感温2种火灾探测器进行合理有效的布置,经过数据检验,在最短时间内报警系统有效报警。结果分析表明:不论着火点在建筑的什么位置,只要合理的设置和组合火灾探测设备,就能在第一时间发现火情。证明了软件模拟的方法对古建筑消防设施设置方式的可行性。
For discovering and controlling ancient building fire as soon as possible and making fire prevention investment more economical and effective,real experiments should be needed.However,in view of the fact that real fire tests on ancient buildings are not permitted,Fire Dynamics Simulation software FDS5 0 is adopted.With Mary palace in Shanxi as the example,a physical fire model was established,and the occurrence of fire,the development process of fire and the different distributions of density and temperature with time during the fire spread process were simulated.Simulation result analysis shows that the smoking detectors and thermal detectors have a reasonable arrangement in the Mary palace.And data test indicates that the alarm system can give an effective warning in the shortest time.It is concluded that,no matter where the fire occurs,reasonable arrangement and good combination of detectors can undoubtedly detect the fire in the earliest time,which proves that the simulation method by software is feasible in the arrangement of fire detectors in ancient architecture.
