地铁地面站热环境对运营安全的影响及改进——以北京市亦庄文化园站为例

Impact and Improvement of Thermal Environment on Operational Safety of Metro Ground Stations-Taking Yizhuang Cultural Park Station in Beijing as an Example

为改善轨道交通地面站的夏季高温环境,提升运营的安全性和舒适性,以北京地铁亦庄文化园站为研究对象,采用12台蒸发冷却机组直接送风的方式进行热环境改善,并通过现场温度检测对比和CFD软件建模分析的方法进行验证。结果表明:该方式可使该地面站台夏季平均温降接近5℃。对轨道交通新线建设、工程改造等均具有较强的技术价值和指导意义。

In order to improve the high temperature situation at the ground station of rail transit in summer and enhance the safety and comfort of operation,the Yizhuang Cultural Park Station of Beijing Metro was taken as the research object,and 12 evaporative cooling units were used to directly supply air for thermal environment improvement.The improvement was verified through on-site temperature detection comparison and CFD software modeling analysis.The results show that this method can effectively reduce the average temperature of the platform to nearly 5℃.It has strong technical value and guiding significance for the construction and renovation of new rail transit lines.
