Development of Ground Reinforcement Technique by using Thinned Wood for Contribution to Mitigation of Global Warming and Revitalization of Forestry Activities

本研究主要探讨松散土层中加入细木的地基加固技术的发展。为研究松散粘性土中铺设木材的效果，进行了路堤现场试验和小型模型试验。从而提高了加筋地基的承载能力。进行了小型振动台试验，研究了一种住宅抗土层液化的对策。结果表明，在松散砂质土层中设置林木，可以减轻房屋的下沉。在此基础上，提出了对既有住宅进行改造的对策。

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.
