【摘要】 本文总结在北京地铁进行的地下空间温度的实测结果 ,分析隧道内气温和壁温与售票厅内气温的变化规律。测量结果显示 :当隧道内有列车通过时 ,气温和壁面温度都瞬间升高 ,气温变化幅度较大。车站售票厅内气温不但受地面气温的影响 ,而且还受到列车活塞风的影响。更多还原

【Abstract】 Results of temperature measurement for the underground pace in Beijing subway are summarized. The variation of air and wall temperature and in ticket hall was analyzed. The results show that the air and wall temperature rises instantly with high amplitude of temperature variation, when the train moves through the tunnel. The temperature in ticket hall is influenced not only by atmosphere temperature but by piston action induced ventilation due to the train movement.更多还原
