Abstract
The authors conducted experiments and analysis to confirm the deformation suppression effect of a road embankment with a shallow foundation composed of crushed stones and geosynthetics over liquefying ground. Because previous studies were conducted on embankments with heights of 4 m, the authors additionally conducted a 50 G centrifugal experiment on embankments with a height of 6 m. The configurations of embankments with and without the countermeasure after soil liquefaction were compared and the authors confirmed that the countermeasure suppressed deformation and kept the shape of the embankment sufficiently. The dynamic effective stress reproduction analysis was conducted and the analysis was used to examine the deformation reduction effects of embankments even greater than 6 m in height.
