Abstract
A ground improvement body includes a horizontal plate-shaped upper improvement body and a lattice-shaped lower improvement body. The depth of the lower improvement body is gradually increased from an outer peripheral part of the ground improvement body toward a center part of the ground improvement body. Thus, ground contact pressure of the ground improvement body is balanced between its outer peripheral part and center part.
Claims6
A ground improvement body comprising a horizontal plate-shaped upper improvement body and a lattice-shaped lower improvement body,
- the lower improvement body having a depth that is gradually increased from an outer peripheral part of the ground improvement body toward a center part of the ground improvement body,
- the lower improvement body including at least:
- an outer periphery improvement body that supports columns and footings at the outer peripheral part of the ground improvement body;
- an intermediate improvement body that supports columns and footings that are spaced apart from the columns and the footings supported by the outer periphery improvement body toward the center part of the ground improvement body;
- a central improvement body that supports a column and a footing at the center part of the ground improvement body;
- an outer-side connection improvement body that connects the footings supported by the outer periphery improvement body with the footings supported by the intermediate improvement body;
- and
- an inner-side connection improvement body that connects the footings supported by the intermediate improvement body with the footing supported by the central improvement body, wherein
- a depth D1 of the outer periphery improvement body, a depth D2 of the intermediate improvement body, and a depth D3 of the central improvement body satisfy D1<D2<D3, and
