摘要
通过介绍大跨度预应力混凝土桥梁施工监测监控技术的内容和方法,包括预应力管道摩阻试验、应力测试和变形监测,并结合工程实例,探讨预应力箱梁张拉施工阶段的监测监控技术,为设计变更和保证施工质量提供了科学的依据和参考。
According to the introduction of construction monitoring measurement and controlling technique for long span concrete bridge,which include prestressed pipe friction test,local stress test and deformation monitoring,we can discuss the tension construction monitoring measurement and controlling technique for prestressed box girder with engineering illustrations in the paper and then to provide some scientific basis and references for the design revision,ensure construction quality.
