摘　　要：以上海9号线松江大学城站地上站台为研究对象,利用重叠网格技术模拟列车运动,研究半高安全门下列车活塞风对站台的影响,对单辆列车进站、停站、出站过程中的速度场、压力场进行数值模拟,分析了3种工况下列车活塞风对站台内气流分布和空气质量的影响。结果表明,活塞效应会增加站台的颗粒物浓度,应避免乘客因站台内颗粒物浓度过高而影响健康。Taking the above-ground platform of Songjiang University Town Station of Shanghai Line 9 as the research object,this paper uses overlapping grid technology to simulate the train movement,studies the influence of train piston wind under the semihigh safety gate on the platform,numerically simulates the speed field and pressure field during the process of a single train entering,stopping and leaving the station,and analyzes the influence of train piston wind on the airflow distribution and air quality in the platform under three working conditions.The results show that the piston effect can increase the concentration of particulate matter at the platform,and it is necessary to prevent high concentrations of particles in the station from affecting passengers'health.
