中文摘要：
对于目前中小跨径的装配式空心板梁桥在服役阶段普遍出现的“单板受力”铰缝病害,许多学者通过有限元软件模拟的方法提出了施加横向预应力进行加固的方法,然而实际效果如何却不得而知,为了验证该加固方法的可行性,利用有机玻璃板桥模型做了相关试验,得到的结果与利用有限元软件模拟得到的结果非常吻合,从而通过试验的手段验证了该加固方法可显著地增强装配式空心板梁桥的横向整体性,减少“单板受力”病害的发生.
英文摘要：
To the present small and medium span of fabricated hollow slabs＇ s common ＇ single beam force＇ hinge joint disease during its service stage, many scholars put forward the reinforcing method by bearing transverse prestress through the simulation of finite element software, whereas the actual effect is unknown. To verify the feasi- bility of the method, related test with the organic glass slab model was carried, the result is identical with the finite element software＇ s result. So the conclusion is verified that this method can enhance the transverse integrality of the fabricated hollow slab and reduce the ＇ single beam force＇ hinge joint disease obviously.
