地下人行通道通风措施的合理化建议

The rationalization proposals of ventilation measure for pedestrian underpass

运用CFD软件对地下人行通道进行气流组织模拟,从自然通风及机械通风两方面进行了探讨,结果表明,在通道上空布置天井,改变通道形式以及采用半横向通风方式更能有效地促进通道内的通风换气。

The article carries out airflow simulation of the pedestrian underpass by applying CFD software, and makes an exploration from two as-pects of natural ventilation and mechanical ventilation. Results show that ： it will effectively promote the pedestrian underpass ventilation through setting patio on the top of the underpass, transforming the underpass patterns and using semi-horizontal ventilation method.
