摘要
针对公轨合建桥复杂的结构特性,为了验证其静力性能与安全性,采用数值仿真分析与现场静载试验的方法,对该桥梁关键截面的应变、挠度及支座位移进行系统测试和研究。研究结果表明该桥梁结构强度、刚度、承载能力均满足设计要求,并处于弹性工作状态,支座滑动性能良好,结构设计合理。
In view of the complex structural characteristics of the highway-railway combined bridge,in order to verify its static performance and safety.In this paper,the strain,deflection and bearing displacement of the key section of the bridge are systematically tested and studied by means of numerical simulation analysis and field static load test.The results show that:stiffness and bearing capacity of the structure meet the design requirements,and are in an elastic working state.The sliding performance of the support is good,and the structural design is reasonable.
