Centrifugal Experiments on Seismic Behavior of Seawall Pile Foundation in Dense Sand with Non-uniform Density Distribution

Abstract

This study conducted centrifuge model experiments on two different soil models with varying spatial arrangements of low relative density regions within dense soil. The effects on soil response and seawall pile foundation response were examined. The results showed minimal differences in excess pore water pressure response in the soil and bending strain response in the piles between the two cases. Thus, the spatial arrangement of low relative density regions had little impact.
