摘要
利用日本经验公式、网络模型EVACNET 4和细网格模型软件Building EXODUS,分别对同一建筑空间进行疏散总时间及各楼层疏散时间计算,并对计算结果进行了分析对比。结果表明,通过对三种疏散模型中主要参数进行合理的取值,三种疏散时间预测方法计算疏散总时间的结果近似一致,均能得到较合理的结果。但各楼层疏散时间的计算得到的结果差异较大,反映了不同疏散模型在细节问题处理上的差异性。
Empirical formula, EVACNET4 of the network model and thin software Building EXODUS of the mesh model were used respectively in the same building space to carry on an evacuation to calculate the total time and each floor evacuation time, and then carry on analysis contrast. The results show that the evacuation of three forecasting methods can get similar results on the evacuation total time through taking reasonable value in the main parameters of the evacuation models which could be more reasonable results. But in the evacuation time of each floor has large differences which reflecting the dissimilarity in dealing with details problem of the evacuation model.
