摘　　要：铰缝损伤是空心板桥的常见病害,近年来,注浆修复破损铰缝技术得到研究并推广。本文对典型空心板桥进行有限元分析,重点讨论了铰缝结构的受力状态,并从铰缝构造和铰缝材料两方面开展研究,有针对性的对注浆修复破损铰缝技术提出改进措施,为类似工程提供参考。Hinged seam damage is a common disease of hollow slab bridges.In recent years,grouting technology for repairing damaged hinged seam has been studied and popularized.Based on the finite element analysis of typical hollow slab bridges,the stress state of hinged seam structure was mainly discussed in this paper.Relavant research was carried out from two aspects:hinged seam structure and hinged seam material.Therefore,the improvement measures were proposed for grouting to repair damaged hinged seam,which should provide reference for similar projects.
