| Abstract: | The study briefly overviews the shortcomings of the existing prediction methods for pile foundation settlement, com- bines the characteristics of the pile foundation settlement, in this paper, the gray GM （1,1） model is introduced, and the settle- ment prediction model for both single pile and pile group is established based on the gray GM （ 1,1 ） model, also the modeling principles and process is giverr At last, the empirical analysis is applied by engineering instance, the study shows that the model has good adaptability, can better reflect the deformation discipline of pile foundation settlement, improve the prediction accuracy, so the study result has good engineering applications value and promotion prospects. |
