文章以港珠澳海底沉管隧道为原型,通过建立足尺隧道火灾试验平台,开展实体隧道火灾试验,研究了不同试验工况下隧道内烟气温度随时间的变化规律,着重分析了燃烧稳定阶段温度沿隧道空间的分布特征. 研究结果表明:纵向风速、燃料类型、火源规模和火源位置是影响隧道内烟气分布特征的主要因素;另外,从应用角度,分析了燃烧达到充分发展阶段时不同工况下高温烟气的蔓延范围对人员逃生及救援设施布置情况的影响, 并提出了人员危险范围及设备建议安装高度.

Using the Hong Kong-Zhuhai-Macao subsea immersed tunn el as an example, a tunnel fire test was performed by establishing a full-scale experimental platform, the variation law of the smoke temperature over time under different working conditions was researched and the temperature distribution characteristics along the tunnel at the stable combustion stage were analyzed. The results show that the longitudinal ventilation velocity, fuel type, fire scale and location of the ignition source are the main factors affecting smoke temperature distribution characteristics. Additionally, the hazardous areas for trapped people are presented and the recommended installation heights for rescue facilities are given after analyzing the influence of the spreading scope of high-temperature smoke on the escape of personnel and facility arrangement at the fully burning stage.
