The underlying mechanisms of pile setup in clay soil was investigated in the context of electrokinetics. Load-displacement tests were done at 0, 1, 3, 5 and 10 day intervals on eleven bench scale Stainless Steel friction piles embedded in compacted natural and kaolinite clay soils to determine setup. Measurements confirmed that the pile capacities increased with time indicating occurrence of setup. The correlations of the measured pile setup with electric self-potential, zeta potential as well as the plastic limit, liquid limit and plasticity index of the soils were investigated. For kaolinite clay, a moderate positive correlation was observed between pile setup and the electric gradient in the soil. The zeta potentials of the soils were calculated from measured electroosmotic flows. It was shown that the zeta potentials had a moderate correlation with setup in kaolinite clay. The results indicated that electrokinetic phenomena could be the major contributing factor for pile setup in clay soils. A moderate positive correlation was observed between the time dependent pile capacity and the liquid limit of kaolinite. No correlation was observed between pile capacity and the plastic limit of the soil. A case of pile relaxation was observed in this study that suggested that a soil with favorable properties for setup may exhibit relaxation instead of setup due to disturbances during pile installation.
