摘　　要：隧道空气动力学效应随着地铁列车设计时速的提高愈加明显,列车通过隧道时产生的空气动力学效应对列车运行安全性、乘客舒适性造成了不良影响。虽然关于隧道空气动力学效应的理论研究已经较为扎实,但是针对具体线路的实际效果分析仍然不足。通过理论分析,结合现场试验对阻塞比、运行速度、列车气密性等可能的影响因素进行考量,经过多种运行工况状态下的线路试验,用试验数据验证在运营线路上采取措施所达到的改善效果,并为新建快速地铁线路的设计优化给出了合理性建议。The aerodynamic effect of tunnel has become more and more obvious with the increase of train design speed,and the phenomenon of train passing through the tunnel has a bad influence on the safety and comfort of train operation.Although the theoretical research on the aerodynamic effect of tunnels has been relatively solid,the analysis on the actual effect of specific lines is still insufficient.From the theoretical perspective,this paper considers the factors such as the blocking ratio,running speed and air tightness of the train,and carries out the line test in combination with various operating conditions.By analyzing the test data,the results achieved by the improvement measures are verified,and reasonable suggestions are given for the design optimization of the newly built fast subway line.
