| 摘 要： | 隧道的火灾危险性决定了隧道的消防设计应以保护人员的生命安全为首要目标。为此开发了隧道火灾时的人员疏散计算机模型Tunev ,该模型可以计算隧道内不同位置发生火灾时,人员疏散所需的时间;与火灾数值模拟软件CFD—POENICS3.5相结合,可以计算危险来临时间;通过对两种时间的比较,判断人员疏散的安全性。简述了模型的有关概念,并对工程实例进行了疏散模拟,最后简述了Tunev模型的验证和应用。

| Abstract: | Because of the tremendous fire risks in tunnels, the fire fighting designs of tunnels should first of all ensure the occupants' safety in case of fire incidents. Therefore, tunnel occupant evacuation model "Tunev" is developed. By means of the model “Tunev”, the total evacuation durations for cases in which fires occur at different tunnel locations can be predicted; by means of model “Tunev” assisted by fire simulation code CFD——POENICS3.5, the durations before hazards occur can be predicted; by means of comparing the two sorts of durations, the safety of the tunnel occupant evacuation can be determined. In the paper, the relevant concepts of model "Tunev" is presented, evacuation simulation is made for a tunnel by means of model "Tunev" and the validation and actual application of the model is described. |
