This paper describes the results of oedometer tests, triaxial consolidation tests and consolidation tests by dead weight in tank, using soft reclaimed clay whose moisture content is fairly higher than liquid limit. It has been definitely shown by the test results that the consolidation properties of oedometer tests are almost identical with those of triaxial consolidaton tests and the relation between e and log p of consolidation by dead weight is almost equal to the extension line of that of oedometer in the range of p>0.5g/cm2. Next, it is shown that the total consolidation settlement by dead weight can be estimated using the initial moisture content and the relation between e and log p. Also, the residual settlement can be estimated using the moisture content and the relation between e and log p, or using the relation between ρt-Δt and ρt from the surveying data of settlement for a certain period of time. But, the relation between settlement and time can only be predicted using the relation between ρt-Δt and ρt from the surveying data of settlement.
