城市分段现浇连续刚构桥全过程施工监控
|
摘要
根据某分段现浇连续刚构桥项目,对结构施工全过程的关键性能参数进行监控分析。建立满堂支架施工、预应力张拉、清水混凝土施工和结构合龙等关键节点工程的施工监测与控制方案,并实施一系列监测信息反馈管理,为服务类似工程的施工管控提供了参考。
Based on an in-segment cast-in-place continuous rigid structure bridge project, this paper analyzed the supervision on the key performance parameters during overall process of structural construction. Supervision and control schemes were created for construction of key nodes, such as full scaffold construction, prestress stretching, as-cast finish concrete construction and structure closing, etc., and a series of monitoring information feedback management were carried out, providing references for management and control of similar projects.
