This paper considers comprehensively concerned data of geology and geophysics within 250 km around the Daba power plant and establishes a 3-D finite element model.The struc-tural stress field in the region is simulated by the model and then the seismic hazard there is analyzed.Danger coefficient and quantitative and qualitative differentiation signs of the potential source region are advanced according to differentiation of seismic safty.It is considered that the structural stability is better near the Daba power plant.
