摘要：	Most mountain tunnels are built to allow a short cross over pass and many tunnel entrances and exits are located at high altitudes and on steep slopes. As a result, bridges and shady spots are often located at tunnel exits. This, in turn, often causes accidents caused by slippery road surface during winter season. This paper discusses the use of a pipe heating system using natural energy, such as tunnel spring water and geothermal heat in the tunnel. The Chugoku Region in the western part of Japan was targeted in this study because tunnel spring water in this region is estimated to have relatively high temperature. The study was carried out using the actual spring water at 10 deg C. The water heating experiment was further carried out with the assumption that there would not be sufficient spring water for melting the existing snow which required provision of additional water from other parts of the tunnel. The paper presents the experimental results based on the above.
