摘　　要：空心板桥梁在运营多年后铺装层和主梁间铰缝处多会出现典型的纵向裂缝,严重影响空心板的横向联结性能.文章分析了其产生病害的原因及对策,对比了3个有限元模型计算结果和实桥静载试验结果,研究了不同加固方法对桥梁横向联结性能的影响及其规律.The typical longitudinal cracks of hollow plate bridge on the deck pavement and the hinge joints between main beams will appear after running many years, which seriously affect the performance of horizontal connection. This paper analyzes the causes of disease and the resulting measures, compares three finite element model results with real static load test results, and discusses the different reinforcement methods about horizontal connection performance of bridges and its laws.

关 键 词：空心板桥 横向联结 有限元 加固对策
