The paper discusses the approach to predict future settlement in soft grounds. The inverse analysis method has been proposed, in which the parameters to simulate the long-term consolidation behavior well including the secondary consolidation, can be identified. Firstly, the consolidation tests were conducted with the separate type interconnected consolidation apparatus in which four consolidation cells were connected. The strains and pore water pressures of the four layers were measured. To predict the secondary consolidation, the log t approach was introduced, and for the primary consolidation, the stochastic nonlinear model was employed to consider the nonlinearity and the spatial variability of parameters, and necessary parameters were identified from measured data. By using proposed method, measured settlements and pore water pressures could be predicted well.
