PROBLEM TO BE SOLVED: To provide a ground settlement countermeasure structure which prevents a structural body installed between head sections of piles from being deformed with upward force applied thereto from the ground on the occurrence of ground settlement.SOLUTION: A ground settlement countermeasure structure 10, which comprises piles 3 and a foundation beam 5, is a foundation of a building. The piles 3 are installed under the ground 1 with footings 3a of respective head sections positioned above the ground 1. The foundation beam 5 is installed in a manner that connects the footings 3a. The ground 1 is soft and the foundation beam 5 is constructed above the same with a gap 7 therebetween. The foundation beam 5 is constructed by placing concrete in a form installed on paper spacers 13. When absorbing moisture over time, the paper spacers 13 lose bearing force in a vertical direction. Thus, even though the piles 3 and the foundation beam 5 are lowered when the ground 1 around the piles is settled due to consolidation over time after construction of the ground settlement countermeasure structure 10, the gap 7 can prevent the foundation beam 5 from receiving upward force from the ground 1 on the occurrence of consolidation settlement.SELECTED DRAWING: Figure 1 |
