Abstract

A series of shaking table tests were conducted to clarify the compaction effects of pile driving on sandy soils, and to investigate the failure mechanism of pile foundation in liquefiable soils. The tests showed that the soil in piled zone was densified so greatly that it became non-liquefiable after pile driving. The pore pressure ratios within this zone were far lower than unit. The settlements of pile foundation were mainly caused by the movement of soil beneath pile tips to the liquefied zone which was outside the piled zone. The failure patterns of pile foundation were rather like the Meryerhoff's general shear failure.

Test on Behavior of Pile Foundation in Liquefiable Soils

St. Louis, Missouri

A series of shaking table tests were conducted to clarify the compaction effects of pile driving on sandy soils, and to investigate the failure mechanism of pile foundation in liquefiable soils. The tests showed that the soil in piled zone was densified so greatly that it became non-liquefiable after pile driving. The pore pressure ratios within this zone were far lower than unit. The settlements of pile foundation were mainly caused by the movement of soil beneath pile tips to the liquefied zone which was outside the piled zone. The failure patterns of pile foundation were rather like the Meryerhoff's general shear failure.
