摘要
本文在简要介绍中间法电磁波测距三角高程测量原理基础上,推导了高差计算及精度估算公式;分析了中间法测量代替精密水准测量的必要条件、重要条件和次要条件。通过大量实测数据对比分析,验证了中间法测量代替精密水准测量的可行性,最后给出了中间法测量的实施方案。
The calculation formula and its estimated formula for precision were deduced while introducing the principle of using the middle way electromagnetic wave surveying triangle elevation in the paper. The necessary condition, the important condition and the second condition of using the middle way replaced the exact leveling were analyzed. And the reliability of using the middle way to replace the exact leveling was validated by analyzing the measured data, and the survey plan with the middle way was made in the end.
