To decrease the differential settlement in road on soft alluvial clay, such a floating foundation is useful as column-slab method which is consisting of soil-cement column by deep mixing method and slab by shallow mixing method. In the design, it becomes necessary to estimate a consolidation settlement of soft layer below the tip of soil-cement column. This paper describes that the water content of clay in Saga plain is closely related with its depth, and also with natural void ratio, unit volumetric weight, and e-log p curve. By using there relationships, a consolidation settlement of clay at any depth can be estimated roughly but very easily. The proposed method is useful for the design of floating foundations for small scale structure and also for rough estimation of settlement in column-slab method in road construction on soft ground.
