STRUCTURE OF ARTIFICIAL GROUND

PROBLEM TO BE SOLVED: To prevent horizontal displacement of a sideways flow or the like by stably supporting a structure in soft natural ground using simple artificial ground without a pile, and stabilizing the natural ground. SOLUTION: A floor slab 2 for supporting the structure 1 and a soil improvement body 13 for supporting the floor slab are constructed on the soft natural ground 3, a core material 11 is integrally fixed on the upside of the soil improvement body, the upper part of the core material is projected in the floor slab and fixed, and the soil improvement body and the floor slab are connected to each other through the core material. The soil improvement body is constructed like a grid by arranging a number of soil improvement piles 10 vertically and horizontally in a plan view, the core material 11 is fixed to the upper part of the soil improvement pile located in the intersection of the grids, and the upper parts of the core materials are connected to each other by a tension member 14. Another soil improvement pile 15 is constructed also in a cell of the grid-like soil improvement body. The upper part of the soil improvement body is supported by a batter pile made of the soil improvement pile. The soil improvement body 13 is extended not only to the floor slab, but also to the lower side of an overlaid ground such as a banking 6 constructed in the periphery thereof.
