Characteristics of Vertical Deformation and Profile Analysis for the Capital Circle
Abstract In order to analyze deformation trends, we use the four-period reiteration precision level data of the capital circle to calculate the ground vertical deformation rate for 2001-2005, 2005-2007 and 2007-2014, draw the vertical deformation rate map and the profile map, combining these with the main fracture distribution and activity. The results show that the deformation characteristics mainly give priority to trend movement in the first two periods, presenting ‘east and west to up, north and south to down’, while the latest data show that deformation appears trend turning in both east and west, with an especially sharp sinking in the Zhangjiakou-Bohai tectonic belt. We predict a tendency of strengthening stress field for this area.
