摘要
填筑的高边坡不平行于飞机杨跑道纵轴线,由于有两个坡比,给施工放样样找点带来困难。建立空间平面方程,计算坡顶线的法向线坡比,编程计算施工放样,这种方法的效果是较明显的,工作简单、便捷、高效,放样数据计数准确、可靠。
High fill construction side slope are unparralel to airport axis.Because there is two-scale ratio of it,difficult for layout survey.Establishing the spatial plane equations,calculating the scale ratio of normal direction on the top line of slope,programming and locating,the effect of this method is obvious,it is simple and high efficiency,accuracy and certainty for data of layout calculation are adequate.
