摘要
衡量桥涵构造体放样精度的检测标准是轴线偏差,而放样检测直接获取的是构造体的坐标差,通过建立轴线偏差与坐标差之间的关系可方便地计算出任一点的轴线偏差。
The detection standard, which weighs the layout precision of bridge and culvert, is axis deviation. The layout detection method is to obtain structure objects' coordinate difference, and then the axis deviation is calculated by establishing the relation between axis deviation and coordinate difference.
