摘要
针对地铁车站围岩土体蓄放热量问题,以运行5年的上海地铁12号线某车站为研究对象,对该车站室外空气温度、车站内空气温度及站厅壁面热流密度进行了为期1年的实测,分析了地铁车站围岩土体的蓄放热特性及在维持车站空气温度稳定性方面的积极作用。测试结果表明:地铁车站围岩土体在过渡季与夏季以吸热为主,冬季以放热为主;全年蓄放热量净值为-5743 MJ,吸热量为36069 MJ,放热量为30326 MJ;围岩土体通过蓄放热有效抑制了室外空气温度波动对车站内空气温度的影响。
Aiming at the problem of heat storage and release of surrounding rock and soil of subway stations,this paper takes a station of Shanghai Metro Line 12 which has been in operation for five years as the research object,and the outdoor air temperature,the station air temperature and the wall heat flux density of the station hall are measured for one year.The heat storage and release characteristics of the surrounding rock and soil of the subway station and its positive effect on maintaining the air temperature stability of the station are analysed.The test results show that the surrounding rock and soil of the subway station is mainly endothermic in the transition season and summer,and mainly exothermic in winter.The net annual heat storage and release is-5743 MJ,the heat absorption is 36069 MJ,and the heat release is 30326 MJ.Through heat storage and release,the surrounding rock and soil effectively restrains the influence of outdoor air temperature fluctuation on the air temperature in the station.
