摘要
选用了第一期单位权方差估值作为整个分析过程参照的标准值,分析了变形监测网稳定性,确定了监测网某期中的动点。
In view of the characteristic of deformation measurement, a standard value for whole analysis process is selected by using the unit power variance estimate value of the first adjustment. The unstable points in the deformation monitoring network can be rapidly found by the analytical method for forming the observation pairs.
