| Abstract: | The construction technique of box girder precast segment assembling by short-line method has been applied abroad, while applied in China in recent years. Its key technique was the alignment control technique of precast segment by short-line method. The basic process and characteristics of the method were introduced then. Finally, the mathematics principle and method of alignment control were emphasized. |
