Small scale shaking table tests in a 1-g gravity field were carried out to evaluate effectiveness of a deformation mitigation method for an existing road embankment during liquefaction by using geosynthetics sandwiched between gravel layer and a gabion. The gravel layer could dissipate an excess pore water pressure during liquefaction immediately, and perform as a rigid plate below a slope of embankment. Furthermore, the gabion could confine the slope of embankment and restrain the lateral movement of slope. As a result, these functions could restrain the deformation of embankment, and keep the shape of embankment and flatness of crest.
