预制箱梁预应力张拉是箱梁施工中的关键环节,钢绞线张拉施工质量对控制箱梁质量至关重要,文章通过南水北调中线总干渠一期工程某标段跨渠公路桥工程实例,介绍箱梁预应力张拉过程中的质量控制。文章就施工时质量控制标准的计算进行了浅析,为类似工程箱梁的预应力张拉质量控制提供参考。
Prestressed box girder prestressed tension box girder construction is the key link, the construction quality of steel strand girder control box girder quality is crucial, the article through the South-North Pipeline Phase Ⅰ project , Introduce the quality control during prestressed tensioning of box girder. The paper analyzes the calculation of quality control standards during construction, and provides reference for prestressed tension control of similar box girders.
