摘　　要：从流体力学分析理论入手,通过理想流体的假定,推导了隧道内空气流动的能量方程和动量方程,分析了各种通风阻力和压力计算模式,在此基础上建立了隧道送排式纵向通风的基本理论,提出了送排式纵向通风的关键控制点及压力平衡模式,为特长公路隧道营运通风的理论和应用进行了有益的探索.Based on the hypothesis of ideal fluial and the fluid dynamic analysis, the paper derives the energy equation and momentum equation of air flow in tunnels,analyzes the ventilating resistance and pressure calculating model, establishes the basic theory of longitudinal pressure-suction ventilation of highway tunnels, proposes the key control point and pressure balance model. The theory and application of extra long highway tunnels ventilation are explored.
