摘要
本文以溪洛渡、向家坝出线走廊GPS-C级网高程平差为例,通过对结果的对比,论证了本工程采用二次曲面拟合方案的合理性;利用现有的水准资料,对测区内高程异常情况进行分析,说明高程分区拟合必要性;通过对结果的精度统计,阐明了成果的可靠性。
This paper takes height adjustment of GPS-C network of XiLuoDu＆XiangJiaBa＇ s power lines corridor as an example, by comparison of the results, proved the quadratic surface fitting plan rationality ; Uses the existing level data, analysed the height anomaly situation in the measured area, explained height subarea fitting necessity; By precision statistics for results, expounded the reliability of results.
