刚架拱桥维修加固施工监控分析

Monitoring and Control Analysis for Maintenance and Reinforcement of a Rigid Frame Arch Bridge

依托国道325线阳江段某大桥新桥维修加固工程,介绍了刚架拱桥维修加固方案,通过对拱桥维修加固过程中的主要工序进行仿真分析,从理论上掌握拱桥的受力及位移情况;再通过理论计算与实际监测数据对比分析充分评估拱桥在维修加固过程中的安全状况,为相关桥梁维修加固及施工监控提供参考。

Relying on the National Highway 325 Yangjiang Section new bridge of a bridge maintenance and reinforcement project,intro‐duces the maintenance and reinforcement scheme of rigid frame arch bridge,the main working procedure in the repair and reinforcement of arch bridge is simulated and analyzed,grasp the stress and displacement of arch bridge theoretically;Then the theoretical calculation and the actual monitoring data are compared and analyzed to fully evaluate the safety status of the arch bridge in the process of maintenance and re‐inforcement.It provides reference for bridge maintenance,reinforcement and construction monitorin.
