摘 要: | 分析了中间法三角高程测量代替精密水准测量的条件,针对城市测量的特点,对近地面垂直角(垂距)观测照准误差进行了深入的实验研究,并制定出中间法三角高程测量的观测技术指标。在闹市区进行了大量的中间法三角高程测量实验,证明了在城市可以用中间法三角高程测量代替精密水准测量,实现了快速、高精度高程测量之目的。

Abstract: | We derived the specific conditions of replacing the precise leveling with intermediate trigonometric leveling.Aiming at the characteristics of the urban measurements, we studied the sighting error about vertical angle observations near the ground, and devel-oped the observation technical indicators on intermediate trigonometric leveling.Numerous experiments carried out under different con-ditions proved that the intermediate trigonometric leveling can replace the precise leveling in the urban measurements. |

Keywords: | urban measurement intermediate trigonometric leveling trigonometric leveling rapid and high precision leveling |
