水准测量中标尺倾斜误差分析与改正

阐述了地形起伏地区水准测量中,标尺倾斜误差存在累积性,具有系统误差特征,分析了标尺倾斜误差对水准高差、路线闭合差的影响,提出了通过高差加入标尺平均倾斜改正,来减小标尺倾斜误差对水准测量的影响.通过海阳市水准网数据的分析,论证了上述论点,同时提出利用改正后的附合路线闭合差的均方根误差大小,来筛选最佳平均倾斜量的方法,并根据高差倾斜改正前后网的精度验证了方法的正确性,最后综述了标尺倾斜影响的控制方法.

Analysis and Correction of the Ruler Tilt Error in Leveling

This paper describes the terrain ups and downs in the leveling region,the existence of staff cumulative tilt error with systematic error characteristic,an analysis of staff tilt errors on the difference of elevation,the impact of road closure error,adding the average ruler tilt correction,inclined to deduce the scale of the error of measurement.Haiyang city network through the data analysis,demonstrated that the above arguments,at the same time the use of correct line after the closure error adhesion of the...
