PROBLEM TO BE SOLVED: To provide a ground improvement structure that uses a self-repairing type material at relatively fragile locations, in which the material contains blast furnace slug for exhibiting sufficient self-repairing capability and is mixed with reinforcing fibers for controlling the width of cracks. ! SOLUTION: A self-repairing type ground improvement structure comprises a ground improvement body comprising a plurality of first wall bodies 4A, 4B, ... arranged in a first direction and a plurality of second wall bodies 6A, 6B, ... arranged in a second direction that intersects with the first direction, and performing a liquefaction prevention function by dividing a target ground area into a plurality of blocks surrounded by the wall bodies. The ground improvement body contains a fragile part 10 of which the strength is relatively lower compared to the rest of the ground improvement areas. The fragile part is formed using the self-repairing type material, which is made by mixing reinforcing fibe |
