The seabed deposits of Osaka Bay that has been formed due to the soil supply from the rivers on the sinking base for about 1 million years consist of the alternation of strata of 14-15 clay layers sandwiched by the gravelly sand layers. The clays of marine origin are called "Ma", namely, the Holocene clay is called "Ma 13" underlain by the Pleistocene ones such as "Ma12" and "Ma11" etc. In this paper, the local soil properties of Ma13 and Ma12 in Osaka Bay are introduced together with the compressibility of the quasi-overconsolidated Pleistocene clays based on the geotechnical database.
