摘　　要：在《桥规》（JTGD62）推荐的后张法构件反向摩阻损失计算方法的基础上，提出预应力混凝土后张法构件两端张拉时反向摩阻损失计算的简化方法，对规范进行补充说明，亦可供设计运用规范参考。Based on calculating method of reversed friction drag loss of post-tensioning members stated in Code for Design of Bridges and Culverts （JTG D62）, simplified method on calculation of reversed friction drag loss under stretching and pulling at both ends of prestressed concrete post-tensioning members is developed in this paper, and additional remarks are given in the code, which can also be used as a reference for design and use of the code.

关 键 词：预应力后张法 两端张拉 反向摩阻损失计算
