| 摘 要： | 电磁波测距仪器的广泛应用,极大提高了距离测量的精度,但在水平距离的计算中,却存在一些不恰当的计算方法,因此,有必要对水平距离的计算公式重新审议。从计算水平距离的公式入手,分别讨论了平面控制测量和三角高程测量计算中的水平距离,论证了平面控制测量中倾斜距离化算的正确方法以及利用斜距和水平距离计算三角高程测量的高差计算公式,得出了一些有益的结论。

| Abstract: | Since EDM instrument is used abroad,the precision of the horizontal distance have advanced.But the calculating of the horizontal distance still use the old formulas,so discussing the formulas of horizontal distance is quite necessary.From the formulas of the horizontal distance,this paper discussed the calculation of the horizontal distance in the plan control surveying and trigonometric leveling,demonstrated the method that the slope distance was calculated into the horizontal distance,and proved the formu... |
