Abstract: Before World War II, an ocean floor cable was laid between Nemuro city and kunashiri Island in Japanese northern territory. Then a reinforced concrete structure was built as a communication system in Nemuro City. The structure is located near the beach line of about 12m. The external deterioration is very severe in the cold sea environment due to the penetration of the salt at the splash zone and the many cycles of freezing and thawing over many years. The purpose of this research was to investigate the deterioration of the concrete and the corrosion level of the reinforcing steel in order to predict the service life of the concrete structure. Also, a repair method is studied to preserve this structure.
