Prediction of Long-term Settlement of Aged Stiff Clay Deposits in Osaka Bay Using Elasto-viscoplastic FE Analys

다국어 초록 (Multilingual Abstract)

The compression modeling for the quasi-overconsolidated Pleistocene clays proposed by the authors has been implemented into the finite element procedure in which an elasto-viscoplastic deformation is assumed to occur even in the quasi-overconsolidated region (p0<p<pc).
One-dimensional finite element analysis is adopted for assessing the settlement of Sakishima and Yumeshima Reclaimed islands, whereas the plane-strain finite element analysis is carried out for investigating the deformation of the Pleistocene deposit beneath the sheet-pile composite revetment at Maishima Reclaimed Island. Based on the comparison to the measured data, the predictive accuracy of the proposed procedure is verified for assessing the long-term settlement at the reclaimed islands in Osaka Port.
