摘 要: 采用小尺寸模型试验方法,对火灾时地铁隧道顶棚烟气最高温度与纵向通风风速、火源功率之间的关系进行了研究。试验结果表明,通风风速和火源功率对火灾时地铁隧道顶棚最高烟气温度有较大影响。对比分析公路隧道纵向通风下顶棚最高烟气温度的Kurioka 模型,引入地铁区间隧道修正系数,建立了修正后的烟气最高温度预测模型,可用于地铁隧道火灾时顶棚烟气最高温度预测。
关 键 词: 通风与空调工程;地铁隧道火灾;小尺寸模型;烟气最高温度

Abstract: Relationships of the maximum temperature of smoke near vault in tunnel fires with longitudinal ventilation and heat release rate of fire was studied by small-scale experiments. The results show that longitudinal velocity and the heat release rate of fire has significant influence on longitudinal temperature of smoke near vault in tunnel fires. By comparing the test results of the maximum temperature of smoke with the predicted values using Kurioka model, a modified correlation is proposed by adding a metro tunnel corrected factor. The formula is recommended for the authority to use as a tool in evaluating the maximum temperature of smoke near vault in metro tunnel fires.
Key words: ventilation and air conditioning engineering; metro tunnel fire; small-scale model; the maximum temperature of smoke
