摘要 隧道火灾时拱顶最高烟气温度的预测在隧道防火安全设计中占有很重要的位置,本文通过1/20小尺寸模型实验和全尺寸现场试验对不同纵向风速作用下拱顶最高烟气温度进行了研究。根据隧道全尺寸试验和小尺寸实验研究结果,Kurioka等人通过小尺寸实验所建立的预测模型在纵向风速没有扰乱烟气分层时具有较好的可靠度,可以推广应用到实际隧道工程设计中。 The prediction of maximum smoke temperature around the vault of a tunnel plays a vital role in the fire safety design of tunnels,so 1 /20 scale and full scale experiments were carried out to study the maximum smoke temperature under different horizontal wind velocity.Based on the results of the small-scale and full-scale experiments,it shows that Kurioka model can provide fairly good predictions when the horizontal velocity doesn't disturb the smoke layer,so it can be applied to the design of real scale tunnels.
