摘　　要：根据流体力学和热力学原理,提出了公路隧道火风压及烟流速度(临界速度)的数学计算模型。同时,通过与Heselden计算模型的对比分析,提出了一些见解及建议。In this paper, a set of mathematical formulae for calculation of fire pressure and smog velocity (critical velocity) in highway tunnels has been developed, which is deduced from fluid dynamics and thermodynamics. At the same time, based on comparison between this model and Heselden's mathematical model, some conclusions and proposals are provided.
