This paper introduces the modeling principle, modeling process and accuracy evaluation method of the dynamic non-time-interval GM (1,1) model, and expounds the problem of dimension selection and residual correction in the dynamic non-equidistant GM (1,1) , Combined with examples of settlement monitoring of high-rise buildings, the prediction results of the dynamic non-equidistant residual GM (1,1) model are compared with the measured values. The results show that the dynamic non-equidistance residual GM (1,1) The conclusion of high prediction accuracy of building settlement monitoring proves the feasibility and reliability of the method and is suitable for the settlement monitoring of high-rise buildings.
