PURPOSE:To easily correct the inclination of a structure by a method in which a superstructure is set on a base structure under a condition that slide movement is allowed along the circular line in both vertical and horizontal directions, and a controller for slide movement is provided between the surrounding of the superstrucrure and the base structure. CONSTITUTION:The upside of a base structure 2 and the downside of a superstructure 3 are regulated to meet a concentrically spheric and uneven relationship. A row of sliders 4, e.g., ball bearing, etc., are provided in a cross-shaped form between both the structures 2 and 3. PC steel bars 6 are set between the surrounding of the lower end of the structure 3 and the surrounding wall 5 of the structure 2 and tensed by an oil-pressure jack 7. When the structure 1 is inclined to the left side by a settlement S, its attitude is corrected vertically by loosening the tension of the steel bar 6 on the left side and at the same time by more tensing the steel bar 6 on the right side.
