Keywords:infrared thermography, tunnel face, water inflow, temperature of the tunnel face, blasting heat, water leakage

At the mountain tunnel,temperature is changing as passing the time.That changes is made during the operation of blasting,chopping,face shotcrete by blasting heat,water inflow,water leakage and ventilation.This time, at the two construction site, we measured temperature of the tunnel face which is in construction step by using infrared thermography.Also we measured the leaking point of the shotcrete wall. This report tried to associate the results of the measurement and process happened at the tunnel face.
