摘要
We constructed a 3-dimensional elastic finite element model to simulate fault deformation in the capital region of China.Firstly,we model the observed fault displacements as well as the stress field.Next we consider several possibilities and disturb the boundary constraints to predict the corresponding fault displacements.Modeling results suggest that left-lateral shear stress environment in the Zhangjiakou—Bohai zone controls fault movement in it,and it can explain the left-lateral slip of those faults in the past 40 years.When eastward pressure or southward extension are loaded,the northeast striking faults will slip dextrally.
