Seismic Deformation and Reinforcing Effect Analysis for Geosynthetics Reinforced Embankment Filled on Compaction-improved Foundation

Abstract

This paper describes the results about two-dimensional seismic deformation analyses on geosynthetics reinforced embankment model. This model was supposed to be filled on liquefactive foundation that improved by compaction method. Findings from the analyses about reinforcing effect of geosynthetics reinforced embankment are as follows.
(1) It would not be expected about additional settlement reducing effect for geosynthetics reinforced embankment filled on foundation improved by compaction method.
(2) The embankment could be maintained their function by application of laying geosynthetics. For the range of deformation especially lateral component of embankment is constrained.
