摘　　要：为了进一步了解该施工技术在现代桥梁建设中的应用效果,本文以某桥梁工程为例,通过有限元分析的方式,模拟分析了混合配筋自复位节段拼装桥梁抗震性能。首先,简单介绍了某路桥工程的基本情况,然后以此为基础,通过桥梁结构模型的构建,进而模拟分析了竖向轴压比、钢管壁厚、初始预应力、核心混凝土强度、耗能钢筋配筋率等不同工况条件下桥梁的抗震性能,以期为混合配筋自复位节段拼装桥梁建设提供参考。In order to further understand the application effect of this construction technology in modern bridge construction,this paper takes a bridge project as an example to simulate and analyze the seismic performance of precast segmental self-centering concrete-filled steel tubular bridge by means of finite element analysis.Firstly,the basic situation of a road and bridge project is briefly introduced,then the bridge structure model is established,and the seismic performance of the bridge under different working conditions of vertical axial compression ratio,steel pipe wall thickness,initial prestress,core concrete strength,and energy-dissipating reinforcement ratio is simulated and analyzed,so as to provide a reference for the construction of precast segmental self-centering concrete-filled steel tubular bridge.
