The new-beach-bridge box girder 0# adopted the construction scheme which setting the steel corbel on the thin wall pillar side as mainly holding component,contemporarily using independently designed compound section steel box girder and Behre beam separately as temporary supportting structure system for the vertically and horizontally stressing main girder.

Steel corbel as passing components in steel structure has been widely used, which is often used in industrial and civil construction works in connected location and plays an important role in large-span space structure.

Although a small size,armored concrete bracket always bears some complex force and concentrated stress,which is easy to crack.

The application of the prestressed steel movable support in the construction of the cast-in-place box beam and its checking computations;
