Centrifugal Modeling of Enlarged Base Foundation Subjected to Pull-Out Force

open access: yesSoils and Foundations, 1998
This paper presents the centrifuge modeling of a prototype pull-out test conducted on enlarged base foundation using undisturbed block samples so that prototype values could be possible to extrapolate from model results. Undisturbed block samples were directly procured in specially designed centrifuge model containers to avoid sample disturbance ...
