摘　　要：要在预应力施工中准确控制张拉值并尽量减小误差,就必须弄清钢丝束中各根钢丝应力不均匀程度和各阶段预应力损失情况,并尽可能应用比较精确的计算方法。On the aim of accurate lengthening, reducing errors, controlling irregular deviation of tensile forces and deformations in every stages of stretching, a comparatively accurate measurement method is developed and described in this article.

关 键 词：预应力结构 钢丝束 张拉 控制
