| Research Abstract |
The characteristics of the external forces on the pile foundations from flowing liquefied soil were examined by centrifuge model experiments and numerical analyses. The following results were obtained: The liquid force, resulting from the flow of the liquefied soil is dominant when the ground completely liquefied, while the solid force resulting from the displacement of the liquefied soil was dominant when the ground was in not-perfect liquefaction. The procedure to estimate the external design force was proposed based on the experimental results.
On the other hand, the effectiveness of countermeasures to prevent the flow of the liquefied soil behind quaywalls were examined by centrifuge model tests and numerical analyses. Based on the experimental results the procedures for the estimation of design force on countermeasure walls was proposed.
