| 中文摘要: |
| 针对板梁桥的常见病害形式，采用了横向预应力加固技术并对板梁桥加固前、后建立了有限元模型。通过分析其荷载横向分布规律证明采用横向预应力技术加固板梁桥效果显著。 |
| 英文摘要: |
| 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. |
