In 1993, two large earthquakes attacked Hokkaido, and they caused great damage. The structure of the Seikan Tunnel fortunately received no damage by them. We had constructed the earthquake disaster prevention system for the Seikan Tunnel named "STEAMS". The two large earthquakes mentioned above triggered this system, and STEAMS successfully recorded the behavior of the tunnel structure during and after the earthquake motions. Among others the most characteristic behavior was the large changes of lining strains continuously during a few days after the earthquakes. We suggest that these changes were caused by the increase of underground water pressure around the tunnel due to the earthquake motions. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
