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.

本研究探讨一种在松散土壤中植入疏木的地基加固技术。通过现场和小比例模型试验，研究了在松散粘性土中设置树木的路堤填筑效果。结果表明，加筋土地基的承载力得到了提高。针对某住宅抗液化对策进行了小型振动台试验。阐明了在松散的桑迪层中设置树木可以减轻房屋的沉降。并提出了既有住宅的对策。
