Abstract
This paper describes a repair and reinforcement method for piles in which the foundation has been damaged by a large earthquake. The piles damaged by the 2016 Kumamoto earthquake (MJMA 7.3) were repaired and reinforced by jet grouting. Then the effectiveness of repair and reinforcement was examined by a static axial compressive load test of the pile reinforced by soil improvement columns. Results from the static axial compressive load test proved that it has a performance not less than the allowable bearing capacity in the initial design. Furthermore, we confirmed that the unconfined compressive strength by laboratory tests and radius of the soil improvement columns satisfied the design value.
