摘　　要：基于对某市海心桥超高性能混凝土(UHPC)加固工程,建立了有限元模型进行结构受力分析和抗震性能评估。通过模拟不同强度的地震作用,发现UHPC加固后桥梁的裂纹分布明显减少,抗震性能得到显著提升。实验结果表明,UHPC加固技术能够有效增强桥梁的承载能力和耐久性,降低病害发生率,提高整体结构的稳定性。Based on the reinforcement of Haixin Bridge in a city using ultra-high performance concrete(UHPC),and a finite element model was established for structural stress analysis and seismic performance evaluation.By simulating seismic effects of different intensities,it was found that the crack distribution of UHPC reinforced bridges was significantly reduced,and the seismic performance was significantly improved.The experimental results show that UHPC reinforcement technology can effectively enhance the bearing capacity and durability of bridges,reduce the incidence of diseases,and improve the overall stability of the structure.
