摘　　要：测量数据处理中,稳健估计相较于最小二乘估计有较强的抗粗差能力,本文运用C++编写了一个基于五种不同的稳健估计选权迭代法的CPⅢ高程网平差程序,然后结合某轨道交通工程项目的一段观测的CPⅢ高程数据,通过对比不加粗差和加入粗差时经典最小二乘估计和稳健估计的计算结果,证明该程序的有效性。In measurement data processing,robust estimation has stronger ability to resist gross error than least square estimation.In this paper,we use C++to write a CPⅢelevation network adjustment program based on five different iterative methods of robust estimation,and then combined with a section of CPⅢelevation data of a rail transit project,to prove the effectiveness of the program by comparing the calculation results of classical least squares estimation and robust estimation without gross error and with gross error.
