Geotechnical and Model-Based Analysis of Seismic Performance in Embankments: A review
This study presents an analysis of shaking table tests performed on wrap-faced embankments constructed on soft clay foundations. The experiments involved a model embankment placed within a laminar box mounted on a shaking table, with results validated through numerical simulations. Tests were conducted under varying surcharge loads and base acceleration levels to assess embankment performance. The influence of base acceleration and surcharge pressures on the embankment’s response was evaluated, with a focus on acceleration profiles at different elevations and face deformations. The experimental setup incorporated earthquake data from the 1989 Loma Prieta event to simulate realistic seismic conditions. Findings reveal that the wrap-faced embankment exhibits considerable resistance to seismic loading, particularly under conditions comparable to the Loma Prieta earthquake. These results provide valuable insights into the seismic performance and design optimization of wrap-faced embankments on soft clay soils.
