Outline of Final Research Achievements

In the framework of assessing the safety against liquefaction during earthquakes, bipolar judgment of liquefaction / non-liquefaction has been used in practice so far. In this study, we recognized the degree of liquefaction and studied how to evaluate the liquefaction resistance of the ground. Since the liquefaction damage of the ground can be evaluated based on the amount of deformation remaining after the earthquake, it is clarified how the performance is evaluated depending on the type and density of the soil that composes the ground. Since the results of this research can evaluate the degree of resistance to liquefaction, it can also evaluate the toughness when an external force exceeding the ground motion considered in the seismic design.

Academic Significance and Societal Importance of the Research Achievements

阪神大震災後,設計で考慮すべき地震動のレベルが格段に大きくなり,耐震設計は性能仕様型に移行した.液状化設計においても,地震動を受けた地盤の液状化の発生予測に加えて,地盤‐構造物系の残留変形量を予測する技術,あるいは設計地震動を超える外力が作用した場合の液状化耐性を評価する設計手法が求められている。
本研究課題では、土質材料の靭性評価や間隙水の移動による進行性破壊現象を設計に取り入れるため,特に地盤の地震後の残留変形を支配する土質物性を根本から吟味し,変形が限定的で有限の範囲内で収まる場合と流動的な振る舞いをして致命的破壊につながる場合を明確に区別判定できる手法を用いた性能設計の枠組みを提案した。
