Abstract: To study the different distribution of ground stress under the deep geo-environment, based on the ground stress data of the hard and soft rock, and the results of numerical simulation, we discussed the effect of depth, lithology and structure on the ground stress. The results are as follows: most of the principle stress values of soft and hard rock have a trend of increasing, and the increasing rate is not much difference; the maximum horizontal principle stress of hard rock is higher than that of the soft rock, the difference of three principle stress bearing in hard rock is larger than that of soft rock, and the phenomenon of hydrostatic pressure state will appear in the soft rock; the stress relieving appears in fault fracture zone, and has a significant influence on the maximum horizontal principle stress. Comparing with the effect of fault, fold plays a more important role on the ground stress.
