精密三角高程测量平差模型的试验研究

摘要

从数据处理的角度探讨了削减三角高程测量折光误差的问题，结合新安江电厂监测网的观测数据，对常用的平差模型进行分析、比较，探讨了大气折光对平差结果的影响规律.在此基础上，利用最小二乘配置原理构造了处理折光误差的迭代平差模型，取得了良好的效果.%In this paper,refraction error reduction in trigonometric leveling is discussed from the viewpoint of data processing. According to the observation data at the Xinanjiang power plant,current adjustment models are compared and analyzed. Then,on the basis of least squares collocation, an iterative model is given to dispose the refraction error, and the effect is satisfactory.
