提出一种钢绞线张拉应力实用控制方法，即采用扭力扳手拧紧螺栓，实现对钢绞线张拉和应力水平的控制。研究结果表明：张拉应力值可通过螺栓的拧紧力矩计算公式确定，扭矩系数取值通过试验确定。对完成张拉端锚固后的钢绞线张拉力值进行48 h 连续监测，研究施工阶段钢绞线的张拉应力损失规律。
提齣一種鋼絞線張拉應力實用控製方法，即採用扭力扳手擰緊螺栓，實現對鋼絞線張拉和應力水平的控製。研究結果錶明：張拉應力值可通過螺栓的擰緊力矩計算公式確定，扭矩繫數取值通過試驗確定。對完成張拉耑錨固後的鋼絞線張拉力值進行48 h 連續鑑測，研究施工階段鋼絞線的張拉應力損失規律。

A practical control method of applying the strand tensioning stress was proposed,in which the torque wrench is used to screw down the bolts,to exert and control the tensioning stress in the strand.The experimental results show that:tensioning stress can be calculated by the formula of the tightening torque and the torque coefficient is given by test. After the locking of the anchor end,the stress of strand was monitored continuously in 48 hours to study the tensioning stress loss.
