Abstract
In situ consolidation parameters for Iwakuni clay were investigated in terms of the volumetric strain (εv o) measuring effective overburden pressure of e-log p curve in the standard oedometer test. The prediction of settlement behavior of the test embankment at the Iwakuni replacement airport was performed on the estimated in situ consolidation parameters. The computed settlement behavior used by the in situ consolidation parameters agrees well with the settlementobservations at the test embankment.
