浅铰缝空心板桥横向联系受力分析及加固设计

Shallow hinge joints of hollow slab bridge transverse contact stress analysis and reinforcement design method research

介绍了浅铰缝空心板桥病害类型及病害原因,用有限单元法分析了浅铰缝空心板桥的横向联系受力特点,并根据受力分析结果提出加强桥面铺装配筋和加厚桥面铺装两种改善空心板横向联系的方法,通过详细计算评价了两种方法对改善铰缝受力的效果,为工程项目提供技术参考。

This paper first introduces the reasons and the types of shallow hinge joints of hollow slab bridge of diseases, and use the finite ele- ment method analysis of shallow hinge joints of hollow slab bridge transverse contact force characteristics, and proposed to strengthen the bridge deck reinforcement and thickening of pavement two methods for improving the transverse hollow plate according to the stress analysis results, two methods to evaluate the detailed calculation results, for reference of engineering project.
