大跨度连续刚构桥施工控制

Construction Control for Large Span Continuous Rigid Bridge

结合采用悬臂浇筑施工的大跨度连续刚构桥的工程实例,计算了桥梁各个施工阶段的应力和变形状态,与施工现场的实测数据进行了对比分析。可为其它同类桥型的施工控制提供借鉴和参考。

Based on the construction practice, the methods for stress and linear control of the construction of the large span continuous rigid frame bridge with the cantilevering technique are studied. The stresses and deformation of the bridge in different construction stages are calculated. The calculated results are compared with the field test results. It may be used as reference for the construction of other large span cantilever cast continuous rigid frame bridge.
