摘　　要：阐述城市地下交通联系隧道中环路匝道烟气蔓延的特点及规律,以缩尺寸模型试验分析在环路匝道发生火灾时,不同因素对隧道火灾烟气蔓延规律的影响。针对环路隧道火灾的复杂性和特殊性,提出地下环路匝道发生火灾时,开启主线隧道的纵向通风排烟系统,在环路出口匝道设置射流风机,防止烟气再次进入环路。The characteristics and rules of smoke spread in the loop ramp of urban traffic link tunnel were described. The influence of different factors on the smoke spread in the loop ramp under fire was researched by small scale model. Aiming at the complexity and particularity of loop tunnel fire, the operation of longitudinal ventilation in main tunnel and the set up of jet fan at ramp of loop exit were suggested to prevent the entrance of smoke into the loop.
