Abstract
In the performance-based design concept, the accurate prediction of displacements will be required. For the demand, the observational approaches are very effective in the soft ground engineering. In this research, as an observational method, the particle filter (PF) is employed. The PF can identify the elasto-viscoplastic parameters, and furthermore, not only primary consolidation parameters, but also the secondary consolidation parameters can be identified. To verify the accuracy of the identified parameters, the model test results are used as measured data. Two-dimensional displacements can be measured by the model test, including the shear behavior due to the loading, and log-term displacement data, including the secondary consolidation are obtained. The possibility to identify the parameters affecting the deformation behavior, are verified, and the predictions of the long term settlements are discussed.
