| 520 | a As the demand for efficient travel increased, the train speed is greatly increased and the subway gradually appeared the express train and the slow train. Express trains pass through some stations without stopping. In this case, the pressure transient phenomenon in the tunnel will become severe. In this study, the dynamic mesh simulation is used to study the pressure variations of the tunnel, platform screen door (PSD), and airshaft caused by the piston wind which is generated by the high-speed train passing through the tunnel and station. The effects of train speed, modes of the train passing through the station, number of airshafts and station types on the aerodynamic pressure are analyzed. The results demonstrate that the increase in train speed brings new challenges to the loading capacity of tunnel structure. Airshafts are set at the entrance and exit of the station, which is conducive to the pressure relief of each part of the tunnel structure. Furthermore, a new type of station with two tracks (express line and slow line) is conducted. The peak pressure of PSD is reduced by 48% compared with the conventional station. This study will contribute to the improvement of subway construction and provide theoretical and data support for the operation of the high-speed train. | |
