STUDIES ON DYNAMIC BEHAVIOR OF EMBANKMENTS OVER SATURATED SAND DEPOSIT

Abstract

Dynamic centrifuge tests under 50 G and effective stress analyses (FLIP) were conducted to study the dynamic behavior of an embankment whose prototype height is 3 m. The embankment made of dry sand was constructed on the saturated sand layer whose relative density was adjusted to either 30% or 70%. Sinusoidal input motions with three different levels of peak acceleration amplitude were given. Objective of the study is to investigate the relationship between the magnitude of settlements and the peak amplitude of input acceleration.
