| 摘 要： | 基于现有规范小曲率半径U形预应力筋张拉伸长量缺乏陈述,而该类预应力筋实测伸长值和理论伸长值偏差过大。在目前的工程实践中,往往需要对该类预应力筋做张拉试验,通过结合有关试验总结了该类预应力筋张拉伸长量修正的试验方法和计算方法。

| Abstract: | Little has been presented about the existing small curvature radius U-shaped prestressed tendon,whose practical elongation value and theoretical stretching elongation deviate greatly from each other.Consequently,in the present engineering practice,pre- stressing tests need to be conducted on such a prestressed tendon.By combining relevant tests,the article summarizes testing and calculation method for rectifying the stretching elongation of prestressed tendon. |

| Keywords: | U-shaped prestressed tendon prestressing test stretching elongation rectification |
