在对国内外规范比较与研究的基础上，指出了预应力磨擦损失简化计算范围扩大仍可满足设计精度的要求；补充和修正了现有规范锚固损失计算公式，推导的公式适用范围广。
Based on the comparison and study of domestic and foreign regulations, it is pointed out that the simplified calculation range of pre-stress friction loss can still meet the requirements of design accuracy; the existing formula for the calculation of anchor loss is supplemented and revised, and the formula used has a wide application range.
