摘要
以天津市某高架桥为例 ,介绍了超长曲线预应力束张拉施工阶段的监测技术 ,包括预应力束摩阻系数的测定和预应力筋张拉后箱梁各截面混凝土应力的测试。
According to a Tianjin viaduct project,authors introduce monitoring technologies in tension construction stage of ultra-long curve prestressed steel strands,including determining the friction coefficient of prestressed strands,and testing concrete stresses of every section of box beams after tension of prestressed tendon.
