Engineering Technologies for Steel Structures Applied to Trans-Tokyo Bay Highway Project

摘要

The Trans-Tokyo Bay Highway is a 15.1 km toll road which spans Tokyo Bay from Kawasaki City, Kanagawa Pref., to Kisarazu City, Chiba Pref., and consists of a bridge, an undersea shield tunnel and two man-made islands. Many new technologies were introduced in the construction of this road. Kawasaki Steel participated in this project in: ① development and execution of a jacket type steel revetment, which was the first application of an oil drilling-type jacket to a revetment structure, ② design and erection of a large-scale bridge with long-span and multi-span continuous girders on the sea, and ③ design and installation of a deck-module structure with facilities for the shield tunnelling.
