摘　　要：为应对火灾这种常规性突发性灾难,降低火灾对大空间建筑物及其内部人员带来的灾难性后果,探索有效的应对措施,需要深入理解火灾在大空间建筑物内的发展规律和特点.以典型大空间建筑物为案例,通过建立火灾现场模型,模拟推演大空间建筑物内的火灾场景,对比消防喷淋装置与机械排烟装置对火灾发展过程的影响,获得了大空间建筑内可燃物的热释放率、烟气层温度、烟气层高度等主要参变量随时间变化的数值关系,给出了相应的研究结论.为大空间建筑火灾和消防工作提供了可参考的实验数据.In order to cope with the regular and sudden disaster such as fire,decrease the catastrophic effects on buildings and explore effective countermeasures,deeply understanding of rules and characteristics of fire development in buildings is required.Taken a typical large-space building as an example,fire scenes are simulated and deduced based on field modeling approach.The influences of fire sprinkler and mechanical smoke extraction devices on fire development are studied.The important parameters including heating release rate of combustible,temperature and height of flue gas layer are obtained by simulating.Research conclusion is given by data analysis.It also provides some experimental data for the large space building fires and fire fighting work.
