珠江三角洲多结点水准网严密平差方法研究

Study on the Method of Strict Adjustment Method of for Multi Node Leveling Network in of the Pearl River Delta

在讨论条件平差法的原理与方法的基础上,对多结点水准网的严密平差过程与方法进行了研究,建立了数字化的多结点严密平差程序,有效解决了珠江三角洲多结点水准网的严密平差问题,并对成果精度进行了分析。旨在及时总结流域大规模水准测量中的重要技术问题,为更好地开展珠江流域其它区域统一高程系统建设或其它类似技术问题提供参考。

On the basis of discussing principles and methods of conditional adjustment, this paper has a research is made on rigorous adjustment procedures and methods of multi - node level network, establishes digital rigorous multi - node adjustment procedures has been established, which, aecomplishinges the rigorous Pearl River Delta multi - node level network adjustment efficiently, And analyzes the accuracy of the results has been analyzed. This paper aims at timely summarizing important technical problems in the process of large scale leveling in Pearl River Basin, and provides references for other similar technical problems and for constructing unified elevation system more effectively in other regions of Pearl River Basin.
