CONSTRUCTION OF HAMANA BRIDGE, WORLD'S LONGEST CENTER SPAN BRIDGE

The construction of this 631.8 M long, four-lane bridge across Hamana Lake by Japan Highway Public Corporation was completed in August, 1976 at a total construction cost of 4457 m-yen. It is described as a prestressed concrete bridge built by the dywidag method, and incorporates a centre span of 240 M to facilitate the passage of ships up to 2000 to between the lake and the Sea of Enshu. Diagrams illustrate a general view of the bridge which consists of five span continuous box girders, in which the two main piers are rigidly connected to the superstructure and the four side piers provided with movable supports. All foundations are built of pneumatic caissons with a cross sectional area of 170 sq M for the side span piers and 480 sq M for the main piers. Data are provided on the main features of the bridge, with photographs and diagrams to illustrate stages of construction. Information is presented on design analysis, construction methods, type of foundations, static and seismic investigations for earthquake-proof purposes and on the composition and quality control test results of the concrete used in the bridge. /TRRL/
