ASEISMATIC FOUNDATION STRUCTURE AND ITS EXECUTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an aseismatic foundation structure capable of coping with a situation causing the deformation and movement of the ground such as a large earthquake or a landslide in a foundation of a house or another structure. SOLUTION: An outer foundation 1 is formed along the outer periphery of the structure, and a planar foundation 2 is formed in the outer foundation. The ground is dug down to execute the outer foundation 1 so that the lower end of the planar foundation 2 is located above the lower end of the outer foundation 1. The ground of the whole structure is held by the lower section of the outer foundation 1 to prevent part of the foundation of the structure surrounded by the outer foundation 1 from being moved or dislocated.
