摘要
本文首先用有限元方法对几种不同的地形模型进行了分析。所得的结论是:由于实际地球表面地形的起伏不平,水准测量资料与地形之间具有相关性,即水准点高程变化与该点高程之间呈相关性。最后,本文对今后水准测量资料的分析处理提出了建议。
In this paper, the deformations of several topographic models are analysed with the finite element method, It is concluded that the relativity of observed levelling data to topography is inherent because of the irregularity of the actual eatth surface. Finally, a new method for dealing with levelling data is put forward, which could be of important reference.
