钢绞线张拉伸长值及锚固张拉力的计算作为施工质量的双控指标,在相应规范均已有明确规定,但对在预应力张拉实际施工中的具体量测,各种理论和实践都存在较大差异。文章根据笔者的长期实践就此问题予以介绍,结论可供有关人员参考。
The calculation of the tensile elongation value and anchorage tensile force of steel strand as the double-control index of construction quality has been clearly defined in the corresponding specifications. However, for the concrete measurement of actual construction of prestressing tension, various theories and There are big differences in practice. According to the author’s long-term practice of this article to introduce this issue, the conclusions available for reference.
