On the Separability between Deformation and Gross Errors Based on the Dynamic Adjustment Model

Based on the dynamic adjustment model,the formulae of separability between deformation and gross errors are derived in the Paper.The method is presented for separating gross errors from deformation statistically while executing the statistical test of deformaton model.Furthermore,the separability of a vertical deformation monitoring network is discussed in detail and illustrated with a practical example,and some beneficial conclusions are obtained.
