摘　　要：通过对桥梁结构的定期健康监测,可判断桥梁结构的受力性能和工作状态。以某悬索跨越管道桥为工程背景进行现场监测,分析计算3种荷载工况下各结构部件的应力和变形。实际监测值和理论设计值对比分析表明,该成桥结构符合规范要求,具有良好的受力性能。Through the regular health monitoring of the bridge structure,the mechanical performance and working state of the bridge structure can be determined.In this paper,based on the engineering background of a suspension bridge crossing pipeline,the stress and deformation of each structural component under three load cases are analyzed and calculated.The comparison between the actual monitoring results and the theoretical data shows that the completed bridge structure meets the requirements of the code and has good mechanical performance.
