• At first , the soft of bridge structure , gqjs , is used to calculate the structure of prestressed concrete continuous beam bridge and the deformation and stress of the concrete box beam are given out ; then by measuring and analyzing the datum of the stress in the prestressed steel rope and the stress of section in the concrete box beam , this article presents two ways to identify the reasonable friction deviation factor k between longitudinal prestressed tendons and the wall of duct ( indirectly and directly ) , and discover the regular pattern of prestressed friction loss
  首先运用桥梁结构分析专用软件gqjs对预应力混凝土连续梁桥进行结构计算，得到了各施工工况下混凝土箱梁的挠度和截面应力；然后给出了识别引起结构预应力损失的孔道偏差系数k的两种方法(间接法和直接法) 。通过对测得的预应力索沿程应力和混凝土箱梁截面应力数据的分析处理，得到了合理的预应力孔道摩擦偏差系数及预应力摩阻损失规律。
