| 摘 要： | 预应力质量的控制是连续箱梁施工中的重要组成部分,良好的预应力施工质量是原材、设施、工艺等方面质量控制的集中体现。以陕西省咸阳市渭河横桥预应力混凝土连续箱梁施工为例,针对纵向预应力筋长（曲）线布设、单端张拉之特点,全面阐述加强预应力施工各作业环节质量控制的要点,对工程实践具有重要的参考价值。

| Abstract: | The control of prestress quality is an important component in continuous girder construction.The good prestress construction quality is a synthetical quality control reflection of material,facility and technology.Taking continuous girder construction of cross-bridge prestress concrete on Weihe River in Xianyang City in Shaanxi Province as an example,the control points in strengthening the quality control at each link are expounded based on the characteristics of long line and curve setting of longitudinal prestressed tendon and one-end tension.It can provide reference for similar projects. |
