Abstract Based on a deep resource exploration project in the Plain of North China，six boreholes are arranged at various positions near the faults according to the requirements of mine facilities，mining and ground industrial sites design，and hydraulic fracturing technique is implemented for measurement of in-situ stress. By comparisons of stresses between near and far to the faults，the variability of in-situ stress near the faults and its change rule is revealed. The results have shown that the maximum horizontal principal stress ?[26.35 MPa，55.47 MPa]，stress concentration factor is 1.05–1.44； ?[1.22，1.65]，1.56 in average，which is approximately equivalent to that of far field stress； ?[5.90，22.80]，16.42 in average，exceeding the differential value far to the faults. In the adjacent zone，the orientation of in-situ stress near to the faults will diverse，the variation range of diversion is 0.60°–30.83°，24.2° in average. In-situ stress will evidently change at the lower wall of fault，between the faults，and at the junctions，it presents stress concentration，increase in differential value between horizontal principal stresses，significantly diversion in the orientation of stress and increase in stress increment per hundred meters at vertical depth. It shows significant difference with the change of measuring position.
