| 摘 要： | 市政工程中经常需要测量与设计线路交叉处的现状架空高压线的底部高程。提出一种新的思路,将架空高压线看做其与地面投影垂直面中的一根抛物线,只需要该抛物线上任意3个点的坐标,即可解算出该抛物线的参数方程,进而可以推算该抛物线上所有点的坐标,也即是可以得到该高压线上所有点的高程。

| Abstract: | It is usual to measure the bottom elevation of the current overhead high-voltage line located in the design lines intersections for municipal engineering.A new idea is proposed in this paper,the overhead high-voltage line is regarded as a parabola of vertical plane of the line and its ground projection.When having coordinates of random three points on this parabola,the relevant parameter equation can be resolved and moreover,all of coordinates of all of points on this parabola can be calculated,that means,the elevations of all of points on the high-voltage line can be obtained. |
