Seismic Response of Embankments on Inclined Foundations under Liquefaction Conditions

Abstract

Embankments are critical components of infrastructure systems, serving as road platforms and flood protection barriers. However, they are often severely damaged under seismic loading, particularly when constructed on liquefiable soils. This study investigated the failure behavior of embankments subjected to earthquake-induced liquefaction through a series of centrifuge shaking table tests. Two foundation conditions were considered: horizontal and inclined base foundations. The shaking input had a frequency of 1 Hz with a peak base acceleration of 0.25 g. Test results show that the difference in settlement between horizontal and inclined foundations was minimal, suggesting that foundation inclination exerted only a limited influence on liquefaction-induced deformation. These findings underscore the critical role of soil saturation and liquefaction in governing embankment performance during earthquakes and provide valuable insights for the development of earthquake-resilient design strategies.
