摘要
以上海周家嘴路越江隧道为工程依托,对双层长大盾构隧道的火灾排烟方式进行了分析研究。通过对火灾工况条件下隧道内温度场、能见度和一氧化碳浓度的模拟计算,对疏散通道的设置方案和逃生救援对策进行分析。结果表明,对于此类型隧道,在采取了相应的逃生救援措施后,采用纵向通风方式是安全可靠的。
Based on the project of Zhoujiazui Road Tunnel in Shanghai,the smoking control method of fire for a double-deck long and large shield tunnel is analyzed and studied.According to the simulation calculation of temperature field,visibility and carbon monoxide concentration within the tunnel under the fire condition,the layout scheme of escape route and the countermeasures of escape rescue are analyzed.The result shows that it is safe and feasible to use the longitudinal ventilation mode after the relative escape rescue measures are taken.
