SUPPORTING STRUCTURE AND CONSTRUCTION METHOD FOR STRUCTURE FOUNDATION

摘要

PROBLEM TO BE SOLVED: To make a foundation uneven settlement hard to occur when liquefaction occurs in the ground below the foundation, and to suppress the foundation settlement while preventing inclination of the foundation even if its settlement is just about to occur, when suppressing the settlement of the foundation by utilizing buoyancy (water pressure). SOLUTION: This supporting structure of the foundation 3 is composed of: sheet piles 4 inserted into the liquefied ground 1 to surround the foundation 3 of a structure 2 while being adjacent to the foundation 3 and being continuous in the peripheral direction of the foundation 3; and a light-weight material 6 provided or put in/into a region being deeper than a bottom face of the foundation 3 and surrounded by the sheet piles 4 to let the buoyancy or water pressure received by the light-weight material 6 from the underground water, act on the bottom face of the foundation 3.
