| 摘 要： | 区域精密水准观测路线一般沿道路布设,这将不可避免地出现观测的方向性问题。实验数据分析表明,观测路线的方向性对成果精度有一定的影响,这与复杂的观测环境条件密切相关。本文在大量数据统计的基础上,从不同角度讨论分析,得到近南北向的水准观测精度,尤其是在晴天的情况下明显优于东西向。

| Abstract: | In general practice regional precise leveling is layout along the road, which inevitably produces difference as the direction of observation varies. In this paper, the experimental data analysis shows that the direction of the observation route has a certain effect on the accuracy of the results, which is closely related to the complex observation conditions. Our results suggest that the accuracy of leveling survey in the north-south direction is higher than that in other directions, especially under the sunny day condition. |
