A STUDY ON THE EXPECTED LIFE OF RAILS IN THE SEIKAN TUNNEL

Seikan tunnel, which connects the Mainland of Japan to Hokkaido, is approximately 54 km in total length, and the part of the tunnel located under the bottom of the sea is in a seawater corrosion environment. The rails to be used for the track in the tunnel should have strong resistance to wear and fatigue. The present report concerns itself with an estimate of 60-kg/m rails when applied to the Seikan tunnel. The 60-kg/m rail in its present shape cannot be regarded as being sufficient for the purpose, and it is necessary to improve on its sectional shape for application there. In doing so, the rail should be given a different sectional shape and greater weight. While galvanizing prolongs the rail life by about 5 years, it is necessary to remove zinc completely from the rails in case long rails are adopted, and this will create a problem at the time of field welding.
