大跨度预应力混凝土连续刚构桥的施工监控与分析

Construction Monitoring and Analysis of Large Span Prestressed Concrete Continuons Rigid Frame Bridge

以主跨为90m+150m+90m的预应力混凝土连续刚构桥为例,对其进行了影响桥梁成桥线型和内力的施工过程控制,通过对各施工阶段应力和变形监测,及时对施工过程提出修正,确保了结构成桥线型和内力在规范规定的范围之内,保证了桥梁结构施工质量,使成桥处于安全状态。

based on the construction process of prestressed continuous ririd frame bridge with main span of 90m+150m+90m,the construction process control of the linear and internal force of the bridge is carried out in each construction stage.The constuction process is timely modified to ensure linear and internal force within the given range,so the construction quality of the bridge is guaranteed and the finished bridge is in a safe state.
