摘　　要：为了给连续公路隧道通风设计提供参考,针对连续公路隧道空气污染物的窜流影响,依据相似性原理,讨论了连续公路隧道之间空气污染物窜流影响模型试验的相似性,并结合实际条件,论述了模型试验台设计过程中需要注意的相关问题。结果表明:露天段是实现模型试验相似的重点研究对象,只要保持几何相似并使模型处于紊动射流状态,就能实现原型与模型的速度及浓度相似;所设计的模型试验台运行情况良好,理论计算结果与模型试验台测试得出的试验结果较为吻合,证实了模型试验相似分析的正确性。In view of the channeling effects of air pollutants in continuous road tunnels,based on the similarity principle,the similarity of the model test of the channeling effects of air pollutants in continuous road tunnels was discussed to provide reference for design of continuous road tunnel ventilation.Combined with the actual conditions,the related problems should be considered in the model test rig design.The results show that the open-air section is the focus of the study to achieve model test similarity and the similarity of speed and concentration in prototype and model can be realized when model and prototype are geometrically similar with model being turbulent jet state.The model test rig is running in good condition.The theoretical calculation results are agreement with the experimental test data,which confirms the correctness of the model test similar analysis.
