ARTIFICIAL GROUND STRUCTURE
To provide an artificial ground structure securing strength necessary for concrete and suppressing an influence of a curing sheet on a concrete surface.SOLUTION: An artificial ground structure comprises a support pile, a first girder member, and a floor slab. The support pile includes a plurality of support piles. When a fulcrum where the support pile intersects with a surface of the ground and an upper end panel point are set as nodes and a part of the support pile between neighboring nodes is set as a member between nodes, two support piles driven into the ground to be adjacent to each other in a first direction or a second direction of the plurality of support piles comprise a plurality of members between nodes. The support piles include one reference pile whose protrusion amount from the ground is h0 and one comparison pile whose protrusion amount from the ground is h. When a yield stress of the reference pile is σ0, a yield stress of the comparison pile is σx, an outer diameter of the reference pile is D0, an outer diameter of the comparison pile is Dx, K1=σx/σ0, and K2=D0/Dx, 0.6≤K1×K2≤1.66 is satisfied.SELECTED DRAWING: Figure 1
