摘　　要：利用ANSYS软件对某寒区铁路隧道的瞬态温度场进行分析,得到了外界空气以一定的速度流入隧道时隧道内空气、衬砌及围岩温度场的变化情况,并且对比分析了不同的空气流通速度条件下温度场的分布情况,为寒区隧道的养护维修提供参考。The transient temperature field about the tunnel in cold regions was analyzed when the wind flowed through the tun- nel. The changes of transient temperature field about the air in the tunnel, the lining and the surrounding rock with certain wind speed was got. The distribution situation of transient temperature field with different wind speeds through the tunnel was analyzed, providing a reference basis for the maintenance of tunnel in cold regions.
