Abstract:

The Bai Chay Bridge, spanning a strait within sight of Ha Long Bay, Vietnam’s premier World Heritage site, has the world’s longest center span length of 435 m, as a single plane cable-stayed prestressed concrete bridge, with a bridge length of 903 m.

The foundations for the main piers were constructed by the pneumatic caisson method. Form travelers were used for the cast-in-situ box girder erection by the balanced cantilever method. The main pylons, which extend 91,5 m in height above the deck level were constructed using a climbing formwork system.

The box girder is lightweight with internal steel pipe bracing and prestressing tendons. The design wind speed for the bridge is 50 m/s. Technologically advanced vibration control devices for the stay cables and the pylons were incorporated into the construction.
