摘　　要：运用相似理论建立污水隧道实体模型,并对实体模型进行测试,同时利用CFD专业软件Airpak对隧道模型的通风情况进行模拟。通过测试与模拟结果的对比分析,验证了CFD模拟实验的准确性及可行性。将Airpak用于实体隧道的通风模拟,通过实体隧道通风模拟结果的对比,评价三种通风方式的优劣,并为以后的隧道通风设计提供理论依据和帮助。A scale model of sewage tunnel is made up using similarity theory and tested practically. The ventilation of the model is simulated by CFD software Airpak. Through comparing simulated results with test ones, it is improved to be exact and feasible to simulate tunnel ventilation. Then, tunnel ventilation of the practical engineering is simulated. Based on comparison of the simulated results, three manners of tunnel ventilation are evaluated, which offers theoretical instructions for design of particular tunnel ventilation.
