摘要
本文针对桥梁养护工作中发现的病害问题,进行了资料综合与论证.着重分析了整体式板桥纵向裂缝问题,指出其产生的主要力学原因是横向配筋设计不足,并提出了解决问题的相应措施.
In this paper, the key issue about disease of the longitudinal crack on the plant-girder bridge is studied. It is pointed out that main mechanics reason of the disease is lack in amount of transverse reinforced bars. The corresponding methods for repairing and fixing old bridge are also given.
