| 摘 要： | 采用三维数值模拟方法,对设置有排烟道的隧道进行了火灾烟气控制的稳态、瞬态模拟分析;研究了在多种通风排烟方案及开启不同数量排烟风口的情况下,该隧道火灾烟气的蔓延特性和烟气控制效果。通过对不同工况的模拟比较研究,为设排烟道的隧道推荐了适宜采用的两种控制火灾烟气的通风排烟方案,并从人员疏散的安全性角度证实了所推荐的方案是可行的。为设置有排烟道的隧道火灾烟气控制及紧急通风设计提供理论依据,同时也可指导人员安全撤离和消防扑救。

| Abstract: | Three-dimensional numerical simulations of both steady and transient states were used to analyze the smoke control effect of fires in a tunnel with smoke extracting gallery,and the spreading characteristics and control effect of the smoke were evaluated for cases of several smoke extracting schemes and different number of smoke draft tuyeres.Based on the evaluation,two ventilation schemes for the smoke control of fires have been recommended after the validation of their feasibility from the safety viewpoint... |
