摘要
本文抓住现代化中线测量时设计单位以坐标形式交桩的新特点 ,选择了更适宜的坐标系 ,推导出了统一坐标系中 ,曲线上任意点的坐标计算公式。该组公式只含一个变量 ,简便易懂 ,可计算曲线上任意点的坐标和其放样数据 ,也适应原切线坐标系或切线统一坐标系。适合施工现场操作。
According to the new trait in modernized center line survey of getting coordinates from the Survey and Design Institute,the paper chooses out a more fit coordinate system and derives out a group of new formula for arbitrary point in curve in the system.Having one variable,it is not only simple for understanding,but also fit for original coordinate system.The calculation procedure of layout of the engineering curve may be more convenient.
