| Abstract: | Using the finite element numerical simulation method with the plate tectonic boundary conditions and the characteristics of inner plate tectonic distribution,the basic tectonic stress field of eastern Chinese mainland is simulated.According to the effect situation from adjacent plates,influence of the acting force change on plate boundary to inner stress field of eastern Chinese mainland is analyzed.Comparing with the simulated result,the characteristics of seismic activity for space distribution in eastern Chinese mainland are expounded. |
