The underground utility tunnel is a very important infrastructure in modern urbanization. However, it is true that a lot of problems are being pointed out such as the reduction of air quality, reduction of ventilation volume, dew condensation and non-emission of poisonous gas due to the lack of smoke ventilating facilities in case of a fire breaking out in a utility channel because, in relative contrast to the rise in demand of underground utility tunnels in the city, the factors of underground space had not been reflected properly in the design and construction of underground utility tunnels and its maintenance system. Especially, out of these problems, dew condensation may cause the weakening of structural durability, and inflict damages such as corrosion to indoor facilities and electric leakage of electric power facilities. Therefore, the purpose of this study is to establish a database for the environmental information of underground utility tunnels by measuring the temperature, humidity, surface temperature and air stream velocity in underground utility tunnels, and to use it as base data for determining dew condensation The underground utility tunnel located at Inchon, Korea was selected as the subject for the study. It was measured during the autumn season and winter season, each 3 days. The temperature at the utility tunnel was measured by 0.48oC and 9.35oC, respectively during the operation of mechanical ventilation and the temperature of the outlet increased by 0.66oC and 0.09oC each. The surface temperature of the utility tunnel was measured ?0.48oC on average. As a result of measuring the underground utility tunnel which was the subject of this study, it is considered that there will be almost no damages such as the weakening of structural durability, corrosion of indoor facilities and electric leakage of electric power facilities because the conditions for dew condensation have not been met.
