遠心模型実験装置は，土木構造物の模型に遠心力を加え，地盤内の応力や間隙水圧を高めて，実物スケールの構造物と同様の応力・間隙水圧状態を再現するものである．現在では，地盤工学分野において，実物スケールの構造物での地盤挙動を知るための重要な装置となっている．対象も静的問題，
動的問題，流体と地盤の複合問題などに検討対象が拡がってきている．一方，沿岸域や海域においては，巨大地震や津波，高潮・高波に対する土木構造物の安定性を確保するため，その挙動を解明することが急務となっている．この流れを受けて，当研究所において  年以上使用してきた遠心装置 号機を改修し，巨大地震を再現したり，波や流れを発生したりできる装置を導入することとした．なお，上記の新たな実験ニーズへの対応に加えて，老朽化部分の更新も目的とした．作業は 〜
年の間の  カ年で行った．本稿では，更新した機器や新設の装置を中心的に紹介している．なお，
号機改良型の全体像を把握できるように，遠心装置  号機と  号機の導入経緯や， 号機から  号機
