| 摘 要： | 该文通过闵浦二桥索塔锚固区预应力束的张拉锚固试验,实测了索塔锚固区内环向预应力钢束的孔道摩阻系数、锚圈口摩阻损失、锚固后回缩损失和伸长量等,并将这些结果与理论计算值进行对比。进而结合分析结果对闵浦二桥设计关键参数进行校合、修正,以指导正确施工并控制环向预应力束张拉后的效应满足设计要求。

| Abstract: | Based on the tensioning and anchorage tests of circular prestressed strands in the plane pylon anchorage area of Minpu No.2 Bridge, the article measures the pipe friction coefficient, the loss of friction at the end of anchorage nut, the drawin loss and the elongation after anchorage of the circular prestressed steel strand within the plane pylon anchorage area, and compares these results with the theoretical calculation values. According to the analyzed results, the article checks up and revises the key de... |
