| Abstract: | Aiming at the defects of plate girder bridges,the technique of transverse pre-stressing technique is adopted and the simulated models are established.Through the analysis of the transverse distribution of loads on the plate girder bridge,it is proved that the pre-stressing strengthening measure noticeably improves the plate girder bridge. |
