Abstract: The piston wind and the piston effect, which will be produced when the subway enters or leaves the subway station, have close relationship with the ventilation of railway tunnel and energy consumption of the subway. With the wide application of underground rail transit, how to save energy and money as possible, with the comfort of the stand halls and the platform layers, is a question that the construction and management apartment have to consider. Therefore, the rational utilization of piston wind has important theoretical and practical significance to achieve saving energy consumption in railway transportation. Starting from the causes of piston wind, the factors which influence the size of piston wind was studied systematically. And SES simulation was carried on to explore influencing reasons of the piston wind, and a better choice of the piston wind was pointed out. Rational utilization of piston wind is not only good to achieve further energy-saving effective way, but also provide the theoretical support and provide technical reference for subway design and operation.
