Seismic isolation of earth retaining structures using EPS-Geofoam compressible inclusions.

The objective of this project is to study the effectiveness of an EPS geofoam compressible inclusion as a seismic isolator against seismic lateral pressures. Twocentrifuge testshave been performed on small scale physical models of retaining structures with and without EPS compressible inclusions, generating the first centrifuge data that highlight the seismic isolation capabilities of the material. Finite elemet numerical analyses have also beenperformed that were validated against the experimental data and were subsequently used to model the seismic response of retaining walls.
