Abstract

The present paper addresses the prediction of the behavior of a ground and a reservoir dyke with a retaining wall at the site of a regulating reservoir whose soft soil foundation is improved by using both the usual em-bankment preloading and vacuum consolidation. To evaluate the settlement, a numerical analysis using an elasto-plastic FEM for soil-water coupled problems, incorporating the SYS Cam-clay model, is carried out, and an inverse analysis approach is adopted. The particle filter is used to identify the geomechanical parame-ters based on the measured settlement. A prediction of the surface deformation and the displacements at the crown of the precast retaining wall is performed using the identified parameters.
