【Abstract】 Air quality model for roadway tunnel was developed using atmospheric diffusion equation and some parameters of the model were discussed. Analytic concertration distributions for air quality models equipped with natural, longitudinal, transverse and semi transverse tunnel ventilation systems were given. In addition, these models were used to compute CO concentrations from the emissions of motor vehicles inside three road tunnels in China. Statistical analysis shown that there were good linear correlation relationships between the calculated and the observed concentrations of CO inside three tunnels and regressive coefficients R 2 was from 0 8499 to 0 9231.更多还原
