Omori Bridge, a 429-m-long I-girder bridge on National Highway 229, suffered the collapse of a 159-m-long section. The bridge spanned a reef that is surrounded by wave-dissipating blocks on the seaward side and precipices on the landward side. On the day of the collapse, waves were extremely high and winds were strong, and abnormal tide levels were attributed to the effect of the local topography. In this research, hydraulic model tests were performed to study the damage mechanism of the bridge and the wave forces that acted on it, in order to assess the safety of the truss bridge that will be erected for temporary restoration. The splash patterns were also examined to determine the conditions under which vehicles can safely run after the restoration.}, pages = {927--932}, title = {台風0418号による大森大橋の被災メカニズムと応急復旧対策について}, volume = {21}, year = {2005}, yomi = {ホンマ, ダイスケ and クボウチ, アツシ and ヤマモト, ヤスジ and ハタケヤマ, アキラ and キムラ, カツトシ} }
