Abstract
In order to maintain the depth of waterways and sea basins, huge amounts of soft clayey soil are dredged at many ports every year in Japan. In recent years, it has become more difficult to secure disposal areas for dredged soil due to environmental and economical restrictions. The effective use of the dredged soils is therefore required. Granular treated soil, which is dredged clay mixed with cement and polymer, has been developed as a countermeasure against this background and expected to be practical uses for reclamation. This paper reports an applicability of the granular treated soil to a reclamation material of artificial seashore. In this study, a centrifuge model test technique was applied for investigating the behaviour of the artificial seashore reclaimed by high permeable granular treated soil in waves. A centrifuge model test is used for simulating the ground behavior in a proto-type scale by small-sized ground model. The wave generated in centrifugal acceleration was similar to real wind wave.
