Abstract: This paper introduces the basic theory and stress mechanism of the composite foundation with sparsely spaced columns and the application of this method in the correction of a building suffering from the differential settlement. The factors that cause the inclination of the building evaluated and the differential settlement mitigation plan is presented. From the analysis of the axial resistance compressive columns, it is concluded that this method is reliable in the differential settlement mitidations.
