摘　　要：在分析桥梁承载力数据过程中注重数据来源的多样性,对其结构内的模糊数据进行极限状态评估,应用软件模型对数据进行模拟,检验桥梁极限承载力是否能达到标准承载力状态;通过了解宽幅空心板桥梁剪力破坏机理设计具有针对性的抗剪加固措施,以及对有限元模型进行加固技术的实现,在试验过程中对桥梁施加剪力,并实施抗剪加固技术,对实施抗剪加固技术前后的抗剪应力数据进行对比,证明了抗剪加固技术的有效性。This paper focuses on the diversified data sources during bridge bearing capacity analysis and carried out limit state assessment for structural fuzzy data.Software model was used for data simulation,to test whether the limit bearing capacity of bridge could reach the standard bearing capacity or not;shear force failure mechanism of wide hollow slab bridge was researched to design specific shear reinforcement measure,and finite element model was used to realize the reinforcement technique.Shear force was applied to bridge during test and shear reinforcement was carried out.The effectiveness of shear reinforcement technique was verified through shear stress data comparison before and after shear reinforcement.
