| 内容記述 | The scheme of executing a mega project of concrete bridge construction for expressway in Japan is reviewed. The autonomous public authority, JH, Japan Highway Public Corporation provided that scheme in which engineers of concerned sectors, i.e., autonomous public authority, industry and university, resonated in productive and progressive mode. The scientific principles put to practice innovatively are; the external prestressing, the replacement of girder webs by the corrugated steel webs, and above all, hybrid of extradosed prestressing and corrugated steel webs (e.g., Himi Yume bridge, JH, in Nagasaki). The construction methods have been invented in which construction procedure shifted from segmental to “fragmental” construction in which the size of structural elements were made smaller so that construction procedures adapt to diversified environment and resources, i.e., natural, industrial and human resources of the area where construction takes place. “Death valley” which is said to exist between technology innovation and its realization onto products has been bridged over by the scheme fit to verify the quality. The internal dissemination of information and transparency by inviting external criticisms for evaluation of the new ideas exceeding the state of the arts are two functions that supported engineering ethics of the in-house engineers. The innovative ideas and the manners of their applications to practices are eventually transferred to and assisted the bridge projects of autonomous local governments which are constantly in short in fund and man power of in-house engineers in recent advocate of “small government” (e.g., Seiun-Bridge, Tokushima prefecture). Concrete bridges built in the last decade became shared heritage, physically, scientifically and methodically. Intelligent resources still exist but not the scheme since 2005 after dissolution of JH as autonomous entity. Whether or not the human resources be orchestrated in future again awaits ingenuity of next generation and experts of concerned trades. | |||||
