地下大型商场火灾时期人员疏散计算机模型

地下商场的火灾危险性决定了地下商场的防火设计应以保护人员的生命安全为首要目标。为此,开发了火灾时期人员疏散计算机模型FEgress,该模型可以计算在建筑物内不同位置处发生火灾时,从火灾发生到人员疏散结束所需的时间,与火灾模拟软件相结合,可以评价火灾时期人员生命的安全性。本文详细阐述了模型的有关概念及计算原理,并简单介绍FEgress的应用。

An occupant evacuation model for the underground shopping mall during fire incidents

Because of the tremendous fire risk in the underground shopping mall the fire design should firstly ensure the occupant's safety during fire incidents. Therefore the occupant evacuation model-FEgress was developed. The model can predict the total evacuation time from the fire start to the end of the evacuation process in various cases in which fire starts in the different location of the building. Combined with fire simulation model it can also assess the fire risk to occupant's life safety. The article describes the theory and some relevant concepts of the model in detail and the model's actual application briefly.
