大跨径变截面连续箱梁桥上部结构施工的质量监控

Quality Monitor in Construction of Superstructure for Large-span Non-uniform Continuous Box Beam Bridge

大跨径预应力混凝土变截面连续箱梁桥上部结构施工风险较大,该文结合几座大跨径预应力混凝土变截面连续箱梁桥上部结构的施工实践,分析了施工过程中容易出现质量问题的环节,提出了预防控制措施。

The greater risk exists in the construction of superstructure for large-span pre-stressed concrete non-uniform continuous box beam bridge.According to the construction practice of the superstructures for some large-span pre-stressed concrete non-uniform continuous box beam bridges,the article analyzes the links easy to cause the quality problems in the course of construction,and puts forward the preventing and control measures.
