摘　　要：对沈阳地铁1号线列车运行时出、入段线隧道,典型区间隧道及典型车站进行了现场测试,并通过自记仪器记录列车运行时的相关参数。通过分析结果表明,隧道入口段空气温度与室外温度同步性较高,合理使用大功率热风幕可以在短时间内有效提高隧道温度,并保证自端点车站起的隧道温度全天高于0°。在冬季活塞竖井关闭的情况下,列车运行热量及站台空气通过活塞效应对区间隧道产生了间歇性的影响,使其空气温度在1摄氏度范围内波动。但隧道空气温度始终低于采暖车站的温度,热量不能有效被车站公共区利用。Shenyang No. 1 line was measured in order to know about the subway tunnel thermal envi- ronment in cold winter. A typical underground tunnel, a tunnel between ground and underground and a typical station were picked as the test content. Test was measured by self- recording instruments to record parameters when train was running. The measurement results show that there exists a high syn- chronism between the entrance of the tunnel temperature and the outside temperature. Reasonable use of high - power air curtain can effectively improve tunnel temperature in a short time, and it will en- sure the tunnel temperature will stay above zero from the first station, which could make the fire pro- tection system avoid freezing without insulating course. The heat produced by train and platform have an intermittent influence on tunnel temperature by piston effects with the piston shaft off. And the air temperature fluctuates in the range of 1 degree Celsius, which always lower than the heating tempera- ture in station. So this energy will not be able to use by the ventilation and air condition system of sta- tion. It is suggested here that using an adjustable ventilation platform doors and realizing its shielding function in winter will be an effective way to prevent energy dissipation.
