管道坐标的计算,锚垫板的安装,张拉应力的计算,预应力筋伸长量的计算,这些都是预应力施工中的重点,既要熟知工艺过程,还要掌握其中的计算原理。
The calculation of pipe coordinates, the installation of anchor plate, the calculation of tensile stress and the calculation of the elongation of prestressing tendons are all important points in prestressing construction. They should not only know the process but also master the calculation principle.
