Abstract:

Multi-surface function method is a traditional and widely used method in the study of vertical crustal movement.Through the two examples of the capital region and Jin-Ji-Meng region,the synthetic model of multi-surface function and movement method is compared with the multi-surface function model and some other models.The results show that the synthetic model of multi-surface function and movement method has a better fitting precision and more stable errors than other several models and it has practical values.

Key words: vertical deformation, multi-surface function, movement method, synthetic model
