Outline of Final Research Achievements

We present a new liquefaction countermeasure technology that uses wood to mitigate ground liquefaction. Because the use of wood effec-tively contributes toward mitigating global warning, we have proposed new applications for its in-ground use. Japan currently has wealthy forestry resources but is in need of environmentally friendly, economically sound measures for ground liquefaction mitigation.
To model the Kochi Prefecture damage is assumed by the Nankai earthquake, we have developed a new liquefaction countermeasure technology for both liquefaction damage mitigation and global warming countermeasures method utilizing log piles.Specifically, the liquefaction measures effect due logs press and verified by a number of in site tests and laboratory tests, CO2 emissions reduction effect by the use of the log, and to verify the ripple effect on the local industry, and the usefulness of the development method It revealed.
