With the development of large-scale offshore reclamation, the long-term deformation of the diluvial clay deposits situated deep in the foundation ground has become an issue, along with the deformation and stability of the alluvial clay deposits sedimented near the seabed. Detailed studies are needed to estimate the above time-dependent behaviors of clay foundation in order to control the harmful effects of ground movements on superstructures and their foundations. Coupled stress-flow analysis, in terms of the elasto-viscoplastic finite element method, is performed to evaluate the deformation and stability of a marine foundation due to the construction of reclaimed land. The calculated performance ascertains a stable process of deformation and the stress state during revetment construction and reclamation. Furthermore, the measured settlement, lateral displacement and excess pore water pressure profiles agree well with the calculated performance.
