一般注記Damage of embankments during earthquakes is widely attributed to the liquefaction of foundation soil. The foundation of an embankment consists of many sublayers of soil from liquefiable sand to relatively impermeable layer, and during earthquakes a mainshock may trigger numerous aftershocks within a short time which may have the potential to cause additional damage to soil structures. Accordingly, the investigation of liquefaction-induced deformation of earthen embankments on various liquefiable foundation conditions under mainshock-aftershock sequential ground motions is carried out by a series of dynamic centrifuge tests. From the test results, it is found that the embankment resting on non-homogeneous soil deposits suffer more damage compared to the uniform sand foundation. The test results also suggest that the sequential ground motions have a significant effect on the accumulated deformation of embankment.
