| Abstract: |
The most difficult problem is that a delayed compression of Pleistocene clays continues even when the total overburden remains less than σ’p. A new procedure is introduced to describe the delayed compression of Pleistocene clays. A series of numerical analyses in terms of the elasto-viscoplastic finite element method is conducted to simulate this time-dependent behavior. The procedure is applied to the long-term deformation that has been monitored at the Maishima Reclaimed Island in Osaka Bay. The calculated results describe well the monitored long-term settlement of each Pleistocene marine clay layer. |
