  1. Beam deviation loss

    波束偏移損耗
  2. 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

    首先運用橋梁結構分析專用軟體gqjs對預應力混凝土連續梁橋進行結構計算,得到了各施工工況下混凝土箱梁的撓度和截面應力;然後給出了識別引起結構預應力損失的孔道偏差系數k的兩種方法(間接法和直接法) 。通過對測得的預應力索沿程應力和混凝土箱梁截面應力數據的分析處理,得到了合理的預應力孔道摩擦偏差系數及預應力摩阻損失規律。
