Abstract

In this paper, two dimensional finite model of elastic mechanics is established according to the geological structure features of Weihe Basin. And the author obtains the stress and strain characteristics by the 2001~2007 GPS data in this region. In the end combine with the characteristic of recently seismic activity in Weihe basin, the relation between crustal deformation characteristics and the seismic activity is also discussed. The results show that current tectonic stress field of this basin presents tensile stress with NNW-SSE direction. The spatial distribution of maximum shear strain rate in Weihe Basin has a very good correlation with small modern seismic belt. The region of Jingyang-Xiany ang-Xi an-Lintong-Sanyuan belongs to the weak zone in the crust of Weihe Basin which is apt to basin extension and earthquake preparation.
