• 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. Samples were also reconstituted in laboratory to compare the behavior of undisturbed and reconstituted models. The undisturbed models showed higher pull-out resistance than that of reconstituted models and suggested the preservation of cohesion and in-situ soil fabric in the undisturbed models. When the results of undisturbed model were compared with the prototype results, a successful prediction regarding pull-out resistance was observed. However, the centrifuge models over predicted displacements of the prototype test. The deviation may arise from the scale and particle size effect due to the lack of similarity in shear band thickness as the peak values of pull-out resistance occur at different displacements. Together with the previously published data, it may be inferred that there might exist a correction factor for displacement in order to match the centrifuge data with the field test data.
