| Outline of Final Research Achievements |
The 2011 Great East Japan Earthquake caused significant soil liquefaction, and many residences were damaged as a result of associated settlement and inclination. This highlighted the importance of seismic countermeasures for small-scale structures. One such measure involves driving logs into the ground to add density. As trees store carbon during growth, logs placed underground below the water table are not prone to deterioration. Based on this characteristic, subterranean log piling represents a dual measure against both global warming and liquefaction.
In this study, liquefaction countermeasure for existing houses by log piling method have been developed by clarifying the effect of carbon storage of log, the effect of reducing energy comparing with the other material, the workability in narrow area and the durability of deterioration.
