| Abstract: | The article introduces the prestressing process and method of a prestressed transfer girder with a span of 28.8m. Test on the girder has verified the prestressing quality and the precision of theoretical calculation of the prestress. It is of referential value for the design and construction of prestressed transfer girder with long span later. |
