小半径弯箱梁桥病害处治分析

Analysis on diseases treatment of small-radius curved box girder bridge

以鄂州地区某弯箱梁为例,着重研究了箱梁采用体外预应力加固前后结构承载力和内力的变化情况以及支座的偏移情况,并针对弯箱梁产生的承载力不足或支座偏移病害,提出了加固处治措施,以保证加固效果。

Taking a curved box girder bridge in Ezhou area as an example, this paper researched the box girder change situation of bearing and internal force using external pre-stressed reinforcement before and after structure and the deviation situation of support, and according to the bearing capacity insufficiency and support deviation diseases caused by curved box girder, put forward reinforcement treatment measures, to ensure the reinforcement effect.
