摘要
Based on the deformation observation data of 11 cross-fault survey points in the capital circle region and taking the two walls of fault as in deformable rigid block, the authors analyze the quantitative relation between the relative sliding of fault plane and relative displacement of the sites on the two walls on the ground surface, and then taking the Tangshan earthquake and its aftershocks as time-bound, the authors divide the fault slip complex or into two time-intervals, fit the regional stress state of the two different time-intervals in the upper crust and find that the stress state in the upper crust inverted by the data of cross-fault deformation observation has changed obviously after the Tangshan earthquake.
