鋼管杭の技術開発と今後の展望

Technical Developments and Future Prospects on Steel Pipe Piles 橋本 正治(Masaharu Hashimoto) 要旨 : 本論文では鋼管杭の現状の利用状況を再認識するとともに,鋼管杭に関する川崎製鉄の技 術開発の歩みと,今後の技術展望について述べた。鋼管杭の利用状況としては鋼管杭の需 要動向と適用分野ごとの要求性能について述べた。川崎製鉄の技術開発の歩みについては, 川崎製鉄の鋼管杭の利用技術が製鉄所の建設を核として確立され,近年では都市部向けの 低振動・低騒音工法の開発などを行うことでその技術をさらに発展させてきたことを述べ た。今後の展望として,将来の性能規定型の設計体系への移行を踏まえ,鋼管杭の性能が 適切に反映されうる環境の整備に努めること,品質の向上・コストの縮減などの時代のニ ーズに即した技術開発を継続することが重要であることを述べた。 Synopsis :

This paper describes the recent circumstances of steel pipe pile usage, the history of technical developments in Kawasaki Steel and the future prospects of the piles. As the circumstances of steel pipe piles usage, this paper shows the demand trend, and required performances in individual application fields. With respect to the history of technical developments, it is described that the application technologies have been established through the construction of steel works in Kawasaki Steel, and later, these technologies have been evolved by the recent developments, such as, low vibration and low noise piling methods for urban area. As the future prospects, it is necessary to make efforts to have the performance of the steel pipe piles properly approved, since the design method will change into performance regulations. Furthermore, it is important to continue to develop the technologies which meet social needs, such as quality improvement, cost down, and so on.
