| 摘 要： | 对于空心板梁桥．目前国内存在的较大问题是板梁受压区不能够满足使用要求。对板梁受压区进行加固处理不仅能提高梁受压区的极限承载力，而且对受拉区极限承载力亦有提高，实践证明这是一种通过对受压区加固从而提高整片梁承载力的方法。

| Abstract: | As for the hollow plate girder bridge, the current existing domestic problems is that the bridge compression zone can not meet the application requirements. The compression zone plate girder reinforcement can improve not only the compression beam ultimate strength, but also the tension zone ultimate bearing capacity. Practice proves that this is an effective method to enhance the beam bearing capacity through reinforcing the compression zone. |

| Keywords: | old bridge hollow plate beam compression zone reinforcement ultimate strength |
