摘要
为准确预测特长公路隧道上机动车CO排放因子,对隧道通行车辆CO排放因子量化分析。选用COPERT模型,预测我国不同排放标准、车型及车速的CO排放因子,建立CO单车排放因子模型。同时,为推算混合车流CO平均排放因子,选取西安市南五台隧道实测,采用质量平衡模型计算机动车CO排放因子,并与模型预测结果对比,研究表明:COPERT模型预测结果与隧道实测CO排放数据吻合,也表明COPERT模型在我国隧道机动车污染物排放因子预测的适用性;最后,对比分析COPERT模型预测结果与PIRAC最新研究成果和我国通风设计规范;COPERT模型预测结果和PIRAC研究结果比较吻合,远低于中国现行通风设计标准给出的CO排放因子。
In order to predict the vehicle CO emission factor of extra-long tunnel,quantitative analysis of vehicle CO emission factors were carried out.COPERT model was selected which was used to calculate CO emission factor with different standards,vehicle type and speed in China,then the CO emission factor for single vehicle was modeled.And then,in order to verify the calculation results of the COPERT model,the comprehensive average CO emission factor of mixed vehicle flow was calculated.Based on the tunnel measurement,the environmental parameters such as temperature,humidity and air pressure in Nan-Wu-Tai tunnel were measured.The mass balance model was adopted to calculate the CO emission factor,and compared with the COPERT predicted results.The results showed that COPERT model predicts were consistent with the tunnel measured data,which is indicated applicability of the COPERT model in China.Compared the predict results of COPERT model with of PIRAC,and China’s current ventilation design standards,the results showed that COPERT model calculation results were in good agreement with the PIRAC research results,but lower than China’s current ventilation design standards.
