The invention belongs to the field of a method for assembling a polycarbonate (PC) continuous box girder by precast segments and by a short line method in the bridge engineering, and particularly relates to a method for performing block-by-block suspension, glue splicing and linear control on precast segments to assemble the PC continuous box girder. The method comprises the following steps: performing block-by-block suspension and glue splicing on the precast segments by a bridge erecting machine until suspension and glue splicing of one hole segment of box girder are finished; tensioning a prestressed beam in the whole hole segment under the suspension state to form a simply-supported box girder; and suspending the simply-supported box girder to a temporary support on the top of a pier by the bridge erecting machine and finishing system transformation. The technical scheme of the invention is reasonable in design; the method is simple; the construction difficult is greatly reduced; the construction efficiency is improved; and the construction time is reduced.
