Soil layer GPS continuous station vertical observation result correction method

The invention discloses a soil layer periodic deformation correction method for a soil layer GPS continuous station vertical observation result. The method comprises the step of correcting the soil layer GPS continuous station vertical observation result according to a soil layer deformation model. According to the method, the soil layer GPS vertical coordinate time sequence observation data are corrected through the soil layer annual period deformation fitting model given by the hydrostatic leveling time sequence, so that the period amplitude of the soil layer GPS vertical coordinate time sequence observation data is reduced, and the vertical observation precision is improved; according to the method, the non-structural deformation soil layer annual period deformation information of GPS observation data is effectively separated, the credibility and reliability of the structural deformation information continuously observed by the GPS are effectively improved, the non-structural deformation research content o
