浅析大跨径预应力混凝土连续刚构桥梁的线形监控

Analysis on Linear Monitoring of Large-span Prestressed Concrete Continuous Rigid Frame Bridge

桥梁施工监控的任务就是根据实际的施工工序,按照已完成工程的结构状态和施工过程,收集现场的参数和数据,对桥跨结构进行实时理论分析和结构验算,分析施工误差状态,采用变形预警体系对施工状态安全度评价和风险预警,根据分析验算结果调整控制参数,预测后续施工过程的结构形状,提出后续施工过程应采取的措施和调整后的设计参数,为今后类似工程的线形监控提供有价值参考。

The task of bridge construction monitoring is to collect the parameters and data of the site according to the actual construction process and the structural state and construction process of the completed project,carry out real-time theoretical analysis and structural check calculation of the bridge span structure,and analyze the construction error state.The deformation warning system is used to evaluate the construction state safety degree and risk early warning,the control parameters are adjusted according to the analysis and verification results,the structural shape of the subsequent construction process is predicted,and the measures to be taken in the subsequent construction process and the adjusted design parameters are proposed,to provide valuable reference for the linear monitoring of similar projects in the future.
