Abstract

From the impact of tsunami due to the Great East Japan Earthquake, Kesen Bridge locating in the Rikuzentakata of Iwate Prefecture was flowed out. Based on the recording data of videos and photographs, shape and features of tsunami acting on the bridge girder are analyzed. As a result, the tsunami acting on the bridges across Kesen River rose in relatively slow pace with the shape similar to steady flow. In addition, numerical simulation was conducted and the validity was confirmed comparing with the video analysis. According to the overall evaluations, the flowing mechanism of Kesen Bridge was figured out to be flowed by steady flow in horizontal direction with the velocity of about 6m/s.
