摘　　要：针对特长公路隧道营运通风的技术问题 ,应用流体力学的基本理论 ,分析了送排式通风压力平衡模式和送排风量间的关联性 ,并在此基础上建立了公路隧道一单元和二单元送排式纵向通风的基本方程 ,提出了一单元和二单元送排式纵向通风的相关控制点 。Aiming at the technique of ventilation in e xtra-long highway tunnel, based on basic theory of fluid mechanics, the relationship between the model of balance for the ventilation pressure and volume of plenum ventilation is analyze d. The basic equation for longitudinal plenum ventilation in first and second un its of highway tunnel is set up and the control points for first and second unit s of highway tunnel are suggested, which serve the basis for investigation of th eory and application of extra long highway tunnel ventilation.
