Centrifuge Model Tests on Dynamic Behavior of Quay Wall Backfilled with Granulated Cement-Treated Soil
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 economic restrictions. Effective use of 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 practically used for reclamation, backfill, or subsoil materials. In this study, a series of dynamic centrifuge tests on applicability of granular treated soil to quay-wall backfill was conducted. The test results indicated that backfill of granular treated soil can reduce lateral displacement of caisson and that such backfill is resistant to liquefaction because of its high permeability.
