The precasting of concrete box girders with short-line match method is applicable to a bridge with considerable numbers of similar spans,girder segments and multiple variations of the girder segment types.

Construction practice proves that the formwork can be conveniently adjustable,generally applicable and can bring into full play the advantages of precasting PC(prestressed concrete) girders by short-line match method.

The designed geometric shape(global coordinate) of a complete prestressed concrete(PC) box girder precast and assembled by the short-line match method is ensured by the geometric shape control of precasting of the girder segments through adjustment of the spatial positions(local coordinate) of the matched segments each time.
