Abstract: A station of Xi’an Metro Line 2 is selected as study object.The wind speed and temperature in running tunnel and piston ventilation shafts of uplink and downlink is analyzed.The airflow movement,piston wind regular pattern of running tunnel and piston ventilation shafts during train running in the coldest month of winter and the hottest month of summer is also studied.According to the result,for the station with platform screen doors,piston wind greatly influence the surroundings of tunnel and piston ventilation shaft.The subway piston wind is significantly influenced by indoor and outdoor difference in temperature,structure of tunnel,the workings of train,air resistance,trains meeting and so on.
