摘　　要：结合工程实际 ,对几个测区已有的资料采用各种拟合方式所得的成果进行统计分析 ,发现同一个测区、同一组起算数据采用不同的拟合方式 ,与水准测得的成果有着显著的差异。为此 ,提出一些通过检验拟合结果以选择拟合方式来获得较为可靠的成果的方法。With the use of observation data in several practical projects, this paper analyzes the GPS leveling results calculated by different fitting models. It is found that there was a significant difference in the heights obtained by these models. A method for testing the fitting reliability is given then.
