摘　　要：当列车快速驶过地下车站时,会产生强烈的瞬态压力波动。本文采用移动模型试验装置研究了列车通过地下车站时列车和屏蔽门表面的瞬态压力分布特征,分析了通风竖井位置对缓解瞬态压力波动的影响。结果表明,不同屏蔽门上对应位置处测点的压力波动值存在差异。通风竖井可以影响压力幅值,不同位置的通风竖井影响特性也有很大差异;位于站台旁边的竖井对缓解列车和屏蔽门表面的瞬态压力幅值效果最好。与没有竖井的车站相比,当竖井设置在站台附近位置时,布置在列车表面上的H2测点的压力幅值减小47.1%,站台屏蔽门表面上的P1测点的压力幅值减小71.3%。When a train passes through underground stations quickly,strong transient pressure fluctuations will generated.In this paper,a moving model experimental device is adopted to explore the distribution of transient pressure on the surfaces of train and platform screen doors when the train passes through an underground station.An analysis of the effect of ventilation shaft locations on alleviating transient pressure was also carried out.The findings indicate that the pressure fluctuations of corresponding monitoring points on different platform screen doors are quite different.The ventilation shaft can affect the pressure peak values,and the influence characteristics of the shaft at different locations are quite different.The shaft located next to the platform has the most profound impact on alleviating the transient pressure amplitude on the surfaces of the train and platform screen doors.In comparison to a station without a shaft,the pressure amplitude of the monitoring point H2 arranged on the train surface can be reduced by 47.1%,and the pressure amplitude of the monitoring point P1 on the surface of platform screen doors decreases by 71.3%when the shaft was set near the platform.
