ABSTRACT
The traditional deformation analysis method will be affected by the noise caused by objective factors such as observation conditions. It requires the observation data to be large samples with a certain characteristic distribution, which is often difficult to meet in actual engineering. This paper adopts the gray system theory to establish a prediction model for the cumulative settlement value. The results show that the model prediction accuracy is high, the calculation is simple, and it does not need a large amount of original settlement value. It provides a reliable analysis method for deformation data analysis and prediction and has reference significance for the deformation observation of large and medium-sized engineering buildings.
