Abstract

 Stress and pore water pressure in seashore soil show complicated responses to breaking waves. Hitherto, it is common to use hydraulic tests performed in gravitational fields to examine soil responses, using a scale model. However, hydraulic tests have shortcomings. For example, it is difficult to reproduce prototype stress and water pressure using such tests, and a large effort is necessary to investigate responses of many seashore-soil types. In this study, it was attempted to introduce a centrifuge test technique to investigate seashore-soil responses in the swash zone. First, the new wave generator was developed because the capacity and area of the centrifuge platform were limited. Second, it was verified under the modelling of models method that hydraulic-test results and pore-water pressures could be reproduced by means of centrifugal acceleration.
