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.

这项研究通过将稀薄的木材安装到松散的土壤中来处理地面加固技术的发展。进行了道路路堤的场和小型模型实验，以研究将木材安装到松散的粘土土壤中的有效性。结果，可以提高加固地面的轴承能力。进行了小规模的摇桌测试，以与土壤液化的住宅房屋进行对策。可以澄清的是，将树林安装到松散的沙质土壤层中可以减轻房屋的沉降。此外，提出了现有房屋的对策。
