摘要
分别采用经典平差和自由网平差两种平差方法对两个工程的沉降观测数据进行数据处理,通过对数据处理的结果进行分析与研究,并对基准点的稳定性进行检验。得出了经典平差和自由网平差在沉降观测数据处理的过程中五点有益的结论。
The paper adopts typical adjustment and rank defect free net adjustment to process the settlement observation data of two projects.Five beneficial conclusions from two methods of adjustment to process the settlement observation data are achieved.
