摘　　要：本文首先阐述了桥梁监控的目的,在此基础上依托某连续刚构桥监控实例,介绍了桥梁监控的有限元理论计算分析、自适应反馈控制分析和现场监控的主要工作。通过承台水化热监控、立模标高的控制、主梁标高观测、全桥线形监控、施工应力控制等监控工作及对监控结果的分析和利用,使桥梁施工质量处于受控状态,且成桥后的结构线形和内力满足设计要求。First the purpose of the bridge monitoring was explained, then on the basis of relying on a continuous rigid frame bridge monitoring instance, the bridge monitoring of finite element analysis, adaptive feedback control analysis and the main work of field monitoring were introduced. Through the bearing platform of hydration heat monitoring, the formwork erection elevation control, the main girder elevation observation, the whole bridge line shape monitoring, the construction stress test of monitoring work and the analysis and use of monitoring results, make the bridge construction quality in controlled state, and into the structure of the bridge line shape and inter- nal force meet the design requirements
