摘要
本文对中国西部山区大量水准复测资料作了统计计算,对复测高差变化与地形相关现象进行了分类对比分析,结论是:山区精密水准测量结果确实含有系统性的、随观测季节而变化的地形相关误差,其统计量值最大达5.8mm/100m。在分析了此种误差的成因之后,提出了一些削弱误差、突出真实形变信息的方法。
In this paper, a lot of releveling data of mountainous area in western China are calculated statistically.The correlativity of height difference change of releveling with really topography are classified,compared and analyzed.The results show that there are the topographic relevance errors in the precise leveling of mountainous area,which are systematic and changed with season,and whose maximum statistic value may be amount to 5.8mm/100m.Some way for weakening the error and revealing the deformation were put for wared after the causes of error was analysed.
