Abstract:

The aerodynamic effect of trains passing through tunnels and its principles are reviewed in this study. The mechanism of pressure wave propagation and formation in the tunnel and the research methods are presented, the influence of relevant parameters such as vehicle type, speed, tunnel length, and obstruction ratio on the tunnel aerodynamic effect is analyzed. Meanwhile, the measures to reduce the tunnel aerodynamic effect are investigated from two aspects of vehicle body optimization and tunnel structure optimization. Finally, achievements of study on railway tunnel influencing factors and improvement measures are summarized, and prospect is conducted on influence of aerodynamic load on tunnel structure, trains, and accessory structures, vacuum aerodynamic, and tunnel aerodynamic in windy environment.
