犍为岷江大桥维修加固工程施工监控

Construction Monitoring for Repairing and Reinforcement of Qianwei Minjiang Bridge

本文以犍为岷江大桥加固工程为背景,结合加固改造设计方案,通过各施工阶段现场测试和结构计算分析,从线形控制、变形监测与应力监测等方面阐述了施工监控技术及效果。通过施工监控对桥梁线形及内力、挠度情况进行实时反馈,保证与设计一致。

The article takes the background of Qianwei Minjiang Bridge reinforcement project, combines with reinforcement designing, through construction sessions field test and calculation analysis, elaborates the construction monitoring and controlling technology and effect from linear control, deformation monitoring, and stress monitor. The linear and internal force and deflection of the bridge real-time feedback has gained through the construction monitoring, which keeps in accordance with design.
