Design and construction of the Tsurumi Tsubasa Bridge
The Tsurumi Tsubasa Bridge is a single-plane three-span continuous cable-stayed bridge on the Bayshore Route of the Metropolitan Expressway in Yokohama. It has a center span length of 510 m and an overall length of 1020 m. The steel superstructure has a total weight of 38000 t, and the foundation were built by using the pneumatic caisson method. In consideration of the special nature of this construction project, precision standards for fabrication were created based on the Common Specifications for Civil Engineering and the Fabrication Standards for Steel Bridges. In this paper some details of the fabrication procedure and the erection procedure are reported. A number of new technological developments were applied, including a cable damper that utilizes a highly damping rubber pad, a cable anchoring mechanism, on-site welding of the towers and a direct suspension using the free floating barge method. To rationalize measurements for the control items and to analyze shim adjustment settings, the approved integrated cable adjustment system was employed. The Tsurumi Tsubasa Bridge, which has the longest single-plane cable-stayed span of any bridge in the world, was opened on 21 December 1994.
