摘要: 本文结合某既有桥梁，建立桥梁结构有限元模型，模拟计算不同工况下桥梁受力与变形情况，确定桥梁静载试验的监控截面及监控点，通过不同的加载方案，得到了桥梁在不同受力状态下关键部位的变形及受力数据，对比实际监测与理论计算值，对桥梁整体健康安全状况进行评价，为以后桥梁检测中的静载试验及健康状况评价提供一些参考。
Abstract: The force and deformation of bridge under different working conditions are calculated through the finite element model of an existing bridge structure. The monitoring section and monitoring point of the static load test are determined based on the calculation results. The deformation and stress of key parts of the bridge under different stress states are monitored under different working conditions. The health case of the bridge is evaluated by means of comparing actual monitoring data with theoretical calculation data. It provides some references for the static load test and health evaluation of bridge detection in the future.
