摘　　要：文章依托内蒙古自治区绥满国道主干线博牙高速林场隧道工程,通过设置温度监测断面,对隧道洞内气温及不同部位、不同深度的围岩温度进行了监测分析。结果表明:(1)隧道洞内气温随时间呈三角函数变化;(2)离隧道洞口越远,洞内气温年平均值越高,年温度振幅越小;(3)隧道拱脚处的温度低于边墙、拱腰和拱顶的温度,在隧道未贯通时,拱脚与拱顶最大温差可达3℃。Based on the Boya highway tunnel project in Suiman National road in Inner Mongolia,the article performs monitoring and analysis on temperature of the tunnel and surrounding rock under different areas and different depths by setting the temperature monitoring sec-tion.The result shows that：1.the temperature inside the tunnel changes with time by a trigo-nometric function;2.the farther away from the tunnel entrance,the higher of the average temperature inside the tunnel,and the smaller the temperature amplitude;3.The temperature at root pile is lower than that at side wall,haunch and vault.The largest temperature differ-ence between root pile and vault can reach 3℃ before tunnel opening.
