This study deals with a development of ground reinforcement technique by installing thinned wood into the loose soil. Field and small-scale model experiments for road embankment were conducted to investigate the effectiveness of installing woods into loose clay soil. As a result, the bearing capacity of reinforced ground could be increased. Small-scale shaking table tests were carried out for a countermeasure of residential house against soil liquefaction. It was clarified that the installing woods into the loose sandy soil layer could mitigate the settlement of house. Furthermore, the countermeasures for existing house were proposed.
