It has become known that the settlements observed in the diluvial deposits and the numerically calculated results often disagree due mainly to the problem involved in the method of estimating the soil parameters from an e-log p curve. The author proposed a method, in which the e-log p curve is first divided into two parts for primary compression and secondary compression, and the settlements caused by the two parts can be separately calculated. Field measurement of settlement of each clay layer, consisting of alluvial clay and diluvial clay, is conducted at three locations on reclaimed lands in Osaka Bay. The numerical calculations of settlements at these three locations are carried out using the proposed equation and the conventionally used equation, and compared with the field observation. It is shown that the proposed method can estimate the field settlements better than the conventional method.
