The authors have presented valuable centrifuge test data concerning the seismic bearing capacity and settlement of piles in liquefiable soils. Little attention has been paid to this topic and little information is available on vertical pile movement for pore pressure ratios less than one. The authors conducted dynamic centrifuge tests at 80-g on pile groups passing through loose, liquefiable sand and founded in underlying dense sand at scaled depths of 15 and 26 m.
