摘要
针对某个实际的顶部开孔的城市公路隧道自然通风模型实验,分析了隧道内交通车流和隧道气流的相互关系,指出在模型实验时应同时保证这两种流动的相似,确定了需要满足的相似特征数以及模型与原型之间的换算关系。
According to top openings, analyses the experiment similitude of two similarity and the conversion a natural ventilation model experiment about an actual city highway tunnel with mutual relationships between airflow and traffic flow. Indicates that the flows should be ensured at the same time. Determines the criteria numbers in relationships between models and prototypes.
