摘要

纵向通风排烟是我国长大公路隧道发生火灾时通风的主要形式

目前开始应用一种新型的特长公路隧道纵向通风集中排烟方式。本文借助CFD三维数值模拟技术

对两种排烟方式在火灾时的烟气控制效果进行了对比分析

研究了顶部设排烟道时

不同排烟开口大小和排烟口间距对隧道火灾时排烟效果的影响。研究表明:顶部设排烟道排烟较纵向通风排烟有较好的烟气控制效果

排烟口的设置间距和开口大小将影响隧道火灾时的排烟特性。

Abstract

Tunnel longitudinal ventilation system for smoke control was the main form in extra-long road tunnels.A new central smoke extraction system for tunnel fire was introduced with consideration of smoke control.Using three-dimensional numerical simulation technology

smoke control effect and movement characteristics of the two smoke control methods were analyzed.With different smoke open size and spacing

the smoke control effect was studied for tunnel fire in central smoke extraction system.The central smoke extraction system has better effect than longitudinal ventilation system for smoke control.The smoke movement characteristics and control effect were influenced by smoke open size and spacing.
