摘　　要：该工程中对大跨度预应力转换大梁施工过程中设计人员关心的预应力的施加值、摩擦损失、锚固值、徐变、松驰、大梁在各施工阶段中的变形及非预应力筋的应力进行监测,研究分析了监测中出现的一些问题,希望对其它工程有所借鉴。The deformation of the prestressing value, friction loss, anchor value, creep, relaxation and girder in every construction period draws designers＇ concern in the construction process of prestressed conversion girder and stress of non-prestressed reinforcement is monitored. Some problems monitored are investigated and analyzed in hope of providing some experience for other projects.
