- Abstract:
- Taking the Shaanxi Qianling Observatory as an example,we systematically detect and image the temperature in lining for the front,NS,and EW parts of the tunnel using the powerful infrared thermal camera. The results show that lining temperature in the front is much higher,varying from 20.7 ℃ to 14.8 ℃,and exhibits a linearly decrease with an increase in distance from the entrance. The lining temperature in the NS part is slightly higher than the EW part,the mean temperatures are approximately 13.5 ℃ and 13.1 ℃ respectively,but each of which is basically uniform and stable. Generally,slight temperature fluctuations widely exist in three main parts of tunnel,the dispersions are larger at a few individual points among them. Furthermore,temperatures in lining and air are significantly discrepant at the same point,this means the difference is drastic. Additionally,infrared thermograms of the eastern end of tunnel show that the temperature in ceiling is clearly larger than that in the sidewalls.
