Physical models consisting of model Geosynthetic Encased Columns (GECs) placed in a remolded kaolinite bed and an embankment fill atop the GECs are tested by making use of a shaking table. The kaolinite bed is consolidated prior to installation of the GECs and placement of the embankment fill. The entire model constituents are housed in a rigid box container and the walls of the container perpendicular to the direction of shaking table movement are fitted with EPS blocks in order to prevent the reflection of the induced shaking repeatedly to the model. In this paper the strains in the geosynthetic encasement during the earthquake shaking is reported.
