摘要:本研究以北京地铁 2 号线某典型车站为对象,根据理论分析的结果并结合 1:8 缩比尺
寸模型实验和数值模拟的研究方法,重点研究了基于地铁活塞效应地铁车站站台门高度对地
铁车站空气流动特性的影响规律;并进一步分析了基于地铁活塞效应通过地铁车站地面出入
口引入新风流经地铁车站各区域的空气流动规律。研究结果表明:地铁站台门高度变化(半
高或全高)对基于地铁活塞效应地铁车站地面出入口的空气流量大小的影响甚微;利用地铁
活塞效应可以实现地铁车站的自然通风换气、有效改善地铁车站的空气品质。

Abstract: This paper took a subway station of line in Beijing as study object, based on the piston
wind characteristics of a field test, a 1∶8 scale model experiment was conducted, bining the
theoretical research and the numerical simulation, analyzed the ventilation effect of the piston wind,
specially the influence on the piston-wind characteristic of the different setting heights of the
Semi-enclosed Platform Doors (SPDs). Results show: little difference of the piston-wind volume exists
when height of the SPDs changes (Enclosed Platform Doors (EPDs) or Semi-enclosed Platform Doors
(SPDs)); t
