五跨预应力混凝土连续箱梁静力性能分析

The Static Performance Analysis of Five-Span Prestressed Concrete Continuous Box Girder

通过有限元仿真分析以及静力性能测试,对某五跨预应力混凝土连续箱梁静力性能进行分析。分析结果显示,桥梁的实际刚度满足设计要求,且有一定的安全储备;有限元仿真分析数值与实测值吻合良好,桥梁的位移和应力满足预期目标和桥梁设计规范要求,桥梁结构处于良好的工作状态。

Through the finite element simulation analysis and the static performance testing, this paper analyzes the static performance of the five-span continuous prestressed concrete box girder. The analysis results show that the actual stiffness of the bridge meets the design requirements and has a certain security reserve. The values of the finite element simulation analysis are well consistent with the real testing values, the displacement and stress of the bridge achieve the expected goal and meet the standards of the bridge design, and the bridge structure is in a good operation state.
