Prediction of resuidial settlemet of soft grounds by using particle ilter

Abstract

In the performance-based design concept, the chances in which the limit state of the displacements is speciied, will increase. Under the situation, the more accurate prediction of displacements will be required, and the observational approach have been developed for the soft ground engineering. In this research, as an observational method, the particle ilter (PF) is employed. The PF can make the identiication of the elasto-viscoplastic parameters possible. Particularly, several sampling methods to generate the particles, which mean the displacements and the pore water pressures calculated from the Monte Carlo method, are examined, and the effective method is discussed. Furthermore, not only primary consolidation parameters, but also the secondary consolidation parameters are identiied in this study.
