摘要
对某城市隧道采用自然通风方案和三种机械通风方案进行了介绍，指出了机械通风常见的问题并提出了解决方案，通过评估发现这样能够节能35%-45%。从经济性角度对四种通风方案进行了对比，所得结论是采用自然通风方案总投资可以节约30%左右，具有显著的经济效益。最后对四种方案进行了综合比较，为公路隧道通风工程的设计提出了合理的建议。
The natural ventilation design and three mechanical ventilation designs when adopted in a city highway tunnel was introduced, the familiar questions in mechanical ventilations were pointed out and the relevant solutions were put forward, in this way 35% -45% energy can be saved. Economic analysis on natural ventilation mode and three mechanical ventilation modes adopted in a city tunnel was conducted, h concludes that the natural ventilation can reduce the total investment by 30% and has remarkable economic efficiency. At last four kinds of ventilation scheme synthetically were compared, then pertinent suggestions to the ventilation design of highway tunnel was put forward.
