摘　　要：地铁的运行会造成隧道区间温度的不断上升从而导致地下空间热环境恶化,可以在地铁隧道壁面铺设毛细管换热器,利用热泵系统排出隧道内的热量.通过数值模拟的方法研究了毛细管壁面换热器的降温效果,分析了隧道内热环境的变化情况,并对距隧道中心不同距离处的岩体温度进行了对比分析.结果表明,在地铁隧道壁面铺设毛细管换热器可有效改善地铁热环境.The operation of the subway tends to cause the temperature in the tunnel section to rise and the thermal environment of the underground space to deteriorate.A capillary heat exchanger can be laid on the wall of the subway tunnel,and the heat in the tunnel can be exhausted by the heat pump system.The numerical simulation method is used to study the cooling effect of the capillary wall heat exchanger,and the variation of the thermal environment in the tunnel is analyzed.The temperature of the rock mass at different distances from the center of the tunnel is compared and analyzed.The results show that laying a capillary heat exchanger on the wall of the subway tunnel can effectively improve the thermal environment of the subway.
