对射流通风技术在公路隧道中的应用，从理论上进行了初步分析。应用流体运动的相似理论，探讨了射流通风系统模型试验的相似律。通过模型试验，在动力射流的基本特性、阻力射流的压降以及在分段吸出式通风系统中的射流调压等方面获得了一些基础数据，并提出了一些相应的计算方法。通过试验还对基本流动的速度分布和静压分布进行了测试，为流场分析提供了基本依据。
The application of jet ventilation technology in highway tunnels is analyzed theoretically. Using the similarity theory of fluid motion, the similarity law of jet ventilation system model test is discussed. Through the model test, some basic data are obtained in the basic characteristics of the power jet, the pressure drop of the resistance jet and the jet pressure regulation in the sub-suction ventilation system, and some corresponding calculation methods are put forward. The velocity distribution and static pressure distribution of the basic flow were also tested through the experiment, which provided the basic basis for the flow field analysis.
