摘　　要：在沈阳地铁二号线世纪广场站的站台层设置多个测点,利用多通道热球式风速仪进行站台层风速的测试,分析站台两端、扶梯口及站台中部各断面速度场的变化规律。测试结果表明,对于北方严寒地区采用全高非封闭式屏蔽门地铁车站,受列车活塞风影响,列车进出站时站台各测点最大风速瞬时可达到3.7m/s,站台平均风速不超过2.5m/s,活塞风持续时间200s,地铁站台的风速可以满足规范的要求,活塞风可以对站台起到辅助通风的作用。In order to obtain the effect on the velocity field by the piston wind on subway station with the full-height non-enclosed screen doors in northern cold region,a number of experiments were progressed with the hot-bulb anemometer at century square station platform of metro line 2 in Shenyang,aiming to test the dynamic rules of the velocity field in each section which included the both sides of platform layer,the egress section of escalators,and the central section,etc.By the piston winds,the maximum wind speed of the side section instantaneously reach 3.7m/s when the train enter into or get out of the station,the average wind speed do not exceed 2.5m/s,and the piston action wind can sustain 200 seconds.For subway station with full-height non-enclosed platform screen doors in northern cold region,the wind speed can meet the specification requirement and the piston wind plays the role of auxiliary ventilation for the subway station.
