| Abstract: | The vertical crustal movement velocity field in Hebei is calculated using the GAMIT/GLOBK software with GPS observational data of the first??stage stations of Hebei CORS network in the past four years. The results show that the mainly vertical crustal movement is a downward motion and that southeast plain region is a serious settlement area in Hebei. The cumulative subsidence in the past three years is more than 150 mm in part areas. And the vertical descent rate in November is faster than that in April. The larger difference of rate has more than 10 mm/a. The model of vertical crustal movement velocity field in Hebei is established based on the method of multiquadric functions and 6′×6′grid velocity is calculated and the isoline map of vertical movement velocity is drew. |
| Keywords: | vertical movement velocity field deformation analysis multiquadric functions grid velocity |
