Load transfer mechanism of piled embankments : centrifuge tests versus analytical models

Résumé

Measured loads in centrifuge tests on piled embankments were compared with values calculated by using three analytical arching models. The Zaeske and van Eekelen models use sets of arches that give the direction of the load transfer and result in an increasing load on the soft soil with increasing embankment thickness or surcharge load, which matches the measurements. The Svanø model, however, assumes that the load on the soft soil remains constant with increasing embankment thickness or surcharge load, thereby being transferred directly to the piles. Therefore, the Zaeske and van Eekelen models match the measurements better than the Svanø model. The van Eekelen model slightly overestimates the pile efficiency for relatively shallow embankments, but matches the measurements better than the Zaeske model for increasing embankment thickness or surcharge load.
